When I started a project in Dash I had very little resources to resolve my doubts. I had to figure it out with the help of dash documentation and only a couple other sites. So this is to help you beginner to start with dash and create you own dashboards.
What is Dash?
If you are looking for a way to represent your analysis and prediction on a simple and pretty dashboard, then Dash is the answer. Dash is a python framework mostly used for building data visualisation apps. It is written on top of Flask, Plotly.js and React. Now, you don’t need to worry if you are not aware how all of these work because Dash is really simple and straightforward to implement, you’ll see!
Dash apps are rendered in the web browser and it is cross-platform . You can deploy your apps to the servers and share them via URLs.
Dash is super easy to learn, comprehend and implement. If you know HTML & CSS, dash is piece of cake for you. Now you just need to know the syntax.
Exploratory data analysis is used by data scientists to analyze and investigate data sets and summarize their main characteristics, often employing data visualization methods. It helps determine how best to manipulate data sources to get the answers you need, making it easier for data scientists to discover patterns, spot anomalies, test a hypothesis, or check assumptions. EDA is primarily used to see what data can reveal beyond the formal modeling or hypothesis testing task and provides a better understanding of data set variables and the relationships between them. It can also help determine if the statistical techniques you are considering for data analysis are appropriate or not.

If we want to explain EDA in simple terms, it means trying to understand the given data much better, so that we can make some sense out of it.
We can find a more formal definition in Wikipedia.
In statistics, exploratory data analysis is an approach to analyzing data sets to summarize their main characteristics, often with visual methods. A statistical model can be used or not, but primarily EDA is for seeing what the data can tell us beyond the formal modeling or hypothesis testing task.
EDA in Python uses data visualization to draw meaningful patterns and insights. It also involves the preparation of data sets for analysis by removing irregularities in the data.
Based on the results of EDA, companies also make business decisions, which can have repercussions later.
In this article we’ll see about the following topics:
Data Sourcing is the process of finding and loading the data into our system. Broadly there are two ways in which we can find data.
As the name suggests, private data is given by private organizations. There are some security and privacy concerns attached to it. This type of data is used for mainly organizations internal analysis.
This type of Data is available to everyone. We can find this in government websites and public organizations etc. Anyone can access this data, we do not need any special permissions or approval.
We can get public data on the following sites.
The very first step of EDA is Data Sourcing, we have seen how we can access data and load into our system. Now, the next step is how to clean the data.
After completing the Data Sourcing, the next step in the process of EDA is Data Cleaning. It is very important to get rid of the irregularities and clean the data after sourcing it into our system.
Irregularities are of different types of data.
To perform the data cleaning we are using a sample data set, which can be found here.
We are using Jupyter Notebook for analysis.
First, let’s import the necessary libraries and store the data in our system for analysis.
#import the useful libraries. import numpy as np import pandas as pd import seaborn as sns import matplotlib.pyplot as plt %matplotlib inline # Read the data set of "Marketing Analysis" in data. data= pd.read_csv("marketing_analysis.csv") # Printing the data data
Now, the data set looks like this,
If we observe the above dataset, there are some discrepancies in the Column header for the first 2 rows. The correct data is from the index number 1. So, we have to fix the first two rows.
This is called Fixing the Rows and Columns. Let’s ignore the first two rows and load the data again.
#import the useful libraries. import numpy as np import pandas as pd import seaborn as sns import matplotlib.pyplot as plt %matplotlib inline # Read the file in data without first two rows as it is of no use. data = pd.read_csv("marketing_analysis.csv",skiprows = 2) #print the head of the data frame. data.head()
Now, the dataset looks like this, and it makes more sense.
Dataset after fixing the rows and columns
Following are the steps to be taken while Fixing Rows and Columns:
Now if we observe the above dataset, the
customerid column has of no importance to our analysis, and also the
jobedu column has both the information of
education in it.
So, what we’ll do is, we’ll drop the
customerid column and we’ll split the
jobedu column into two other columns
education and after that, we’ll drop the
jobedu column as well.
# Drop the customer id as it is of no use. data.drop('customerid', axis = 1, inplace = True) #Extract job & Education in newly from "jobedu" column. data['job']= data["jobedu"].apply(lambda x: x.split(",")) data['education']= data["jobedu"].apply(lambda x: x.split(",")) # Drop the "jobedu" column from the dataframe. data.drop('jobedu', axis = 1, inplace = True) # Printing the Dataset data
Now, the dataset looks like this,
Customerid and jobedu columns and adding job and education columns
If there are missing values in the Dataset before doing any statistical analysis, we need to handle those missing values.
There are mainly three types of missing values.
Let’s see which columns have missing values in the dataset.
# Checking the missing values data.isnull().sum()
The output will be,
As we can see three columns contain missing values. Let’s see how to handle the missing values. We can handle missing values by dropping the missing records or by imputing the values.
Drop the missing Values
Let’s handle missing values in the
# Dropping the records with age missing in data dataframe. data = data[~data.age.isnull()].copy() # Checking the missing values in the dataset. data.isnull().sum()
Let’s check the missing values in the dataset now.
Let’s impute values to the missing values for the month column.
Since the month column is of an object type, let’s calculate the mode of that column and impute those values to the missing values.
# Find the mode of month in data month_mode = data.month.mode() # Fill the missing values with mode value of month in data. data.month.fillna(month_mode, inplace = True) # Let's see the null values in the month column. data.month.isnull().sum()
Now output is,
# Mode of month is 'may, 2017' # Null values in month column after imputing with mode 0
Handling the missing values in the Response column. Since, our target column is Response Column, if we impute the values to this column it’ll affect our analysis. So, it is better to drop the missing values from Response Column.
#drop the records with response missing in data. data = data[~data.response.isnull()].copy() # Calculate the missing values in each column of data frame data.isnull().sum()
Let’s check whether the missing values in the dataset have been handled or not,
All the missing values have been handled
We can also, fill the missing values as ‘NaN’ so that while doing any statistical analysis, it won’t affect the outcome.
We have seen how to fix missing values, now let’s see how to handle outliers in the dataset.
Outliers are the values that are far beyond the next nearest data points.
There are two types of outliers:
So, after understanding the causes of these outliers, we can handle them by dropping those records or imputing with the values or leaving them as is, if it makes more sense.
To perform data analysis on a set of values, we have to make sure the values in the same column should be on the same scale. For example, if the data contains the values of the top speed of different companies’ cars, then the whole column should be either in meters/sec scale or miles/sec scale.
Now, that we are clear on how to source and clean the data, let’s see how we can analyze the data.
If we analyze data over a single variable/column from a dataset, it is known as Univariate Analysis.
Categorical Unordered Univariate Analysis:
An unordered variable is a categorical variable that has no defined order. If we take our data as an example, the job column in the dataset is divided into many sub-categories like technician, blue-collar, services, management, etc. There is no weight or measure given to any value in the ‘job’ column.
Now, let’s analyze the job category by using plots. Since Job is a category, we will plot the bar plot.
# Let's calculate the percentage of each job status category. data.job.value_counts(normalize=True) #plot the bar graph of percentage job categories data.job.value_counts(normalize=True).plot.barh() plt.show()
The output looks like this,
By the above bar plot, we can infer that the data set contains more number of blue-collar workers compared to other categories.
Categorical Ordered Univariate Analysis:
Ordered variables are those variables that have a natural rank of order. Some examples of categorical ordered variables from our dataset are:
Now, let’s analyze the Education Variable from the dataset. Since we’ve already seen a bar plot, let’s see how a Pie Chart looks like.
#calculate the percentage of each education category. data.education.value_counts(normalize=True) #plot the pie chart of education categories data.education.value_counts(normalize=True).plot.pie() plt.show()
The output will be,
By the above analysis, we can infer that the data set has a large number of them belongs to secondary education after that tertiary and next primary. Also, a very small percentage of them have been unknown.
This is how we analyze univariate categorical analysis. If the column or variable is of numerical then we’ll analyze by calculating its mean, median, std, etc. We can get those values by using the describe function.
The output will be,
If we analyze data by taking two variables/columns into consideration from a dataset, it is known as Bivariate Analysis.
a) Numeric-Numeric Analysis:
Analyzing the two numeric variables from a dataset is known as numeric-numeric analysis. We can analyze it in three different ways.
Let’s take three columns ‘Balance’, ‘Age’ and ‘Salary’ from our dataset and see what we can infer by plotting to scatter plot between
#plot the scatter plot of balance and salary variable in data plt.scatter(data.salary,data.balance) plt.show() #plot the scatter plot of balance and age variable in data data.plot.scatter(x="age",y="balance") plt.show()
Now, the scatter plots looks like,
Now, let’s plot Pair Plots for the three columns we used in plotting Scatter plots. We’ll use the seaborn library for plotting Pair Plots.
#plot the pair plot of salary, balance and age in data dataframe. sns.pairplot(data = data, vars=['salary','balance','age']) plt.show()
The Pair Plot looks like this,
Since we cannot use more than two variables as x-axis and y-axis in Scatter and Pair Plots, it is difficult to see the relation between three numerical variables in a single graph. In those cases, we’ll use the correlation matrix.
# Creating a matrix using age, salry, balance as rows and columns data[['age','salary','balance']].corr() #plot the correlation matrix of salary, balance and age in data dataframe. sns.heatmap(data[['age','salary','balance']].corr(), annot=True, cmap = 'Reds') plt.show()
First, we created a matrix using age, salary, and balance. After that, we are plotting the heatmap using the seaborn library of the matrix.
b) Numeric - Categorical Analysis
Analyzing the one numeric variable and one categorical variable from a dataset is known as numeric-categorical analysis. We analyze them mainly using mean, median, and box plots.
response columns from our dataset.
First check for mean value using
#groupby the response to find the mean of the salary with response no & yes separately. data.groupby('response')['salary'].mean()
The output will be,
There is not much of a difference between the yes and no response based on the salary.
Let’s calculate the median,
#groupby the response to find the median of the salary with response no & yes separately. data.groupby('response')['salary'].median()
The output will be,
By both mean and median we can say that the response of yes and no remains the same irrespective of the person’s salary. But, is it truly behaving like that, let’s plot the box plot for them and check the behavior.
#plot the box plot of salary for yes & no responses. sns.boxplot(data.response, data.salary) plt.show()
The box plot looks like this,
As we can see, when we plot the Box Plot, it paints a very different picture compared to mean and median. The IQR for customers who gave a positive response is on the higher salary side.
This is how we analyze Numeric-Categorical variables, we use mean, median, and Box Plots to draw some sort of conclusions.
c) Categorical — Categorical Analysis
Since our target variable/column is the Response rate, we’ll see how the different categories like Education, Marital Status, etc., are associated with the Response column. So instead of ‘Yes’ and ‘No’ we will convert them into ‘1’ and ‘0’, by doing that we’ll get the “Response Rate”.
#create response_rate of numerical data type where response "yes"= 1, "no"= 0 data['response_rate'] = np.where(data.response=='yes',1,0) data.response_rate.value_counts()
The output looks like this,
Let’s see how the response rate varies for different categories in marital status.
#plot the bar graph of marital status with average value of response_rate data.groupby('marital')['response_rate'].mean().plot.bar() plt.show()
The graph looks like this,
By the above graph, we can infer that the positive response is more for Single status members in the data set. Similarly, we can plot the graphs for Loan vs Response rate, Housing Loans vs Response rate, etc.
If we analyze data by taking more than two variables/columns into consideration from a dataset, it is known as Multivariate Analysis.
Let’s see how ‘Education’, ‘Marital’, and ‘Response_rate’ vary with each other.
First, we’ll create a pivot table with the three columns and after that, we’ll create a heatmap.
result = pd.pivot_table(data=data, index='education', columns='marital',values='response_rate') print(result) #create heat map of education vs marital vs response_rate sns.heatmap(result, annot=True, cmap = 'RdYlGn', center=0.117) plt.show()
The Pivot table and heatmap looks like this,
Based on the Heatmap we can infer that the married people with primary education are less likely to respond positively for the survey and single people with tertiary education are most likely to respond positively to the survey.
Similarly, we can plot the graphs for Job vs marital vs response, Education vs poutcome vs response, etc.
This is how we’ll do Exploratory Data Analysis. Exploratory Data Analysis (EDA) helps us to look beyond the data. The more we explore the data, the more the insights we draw from it. As a data analyst, almost 80% of our time will be spent understanding data and solving various business problems through EDA.
