Data Validation in Excel

Data Validation in Excel

In this tutorial, let’s discuss what data validation is and how it can be implemented in MS-Excel. Let’s start!!!

What Is Data Validation in Excel?

Data Validation is one of the features in MS-Excel which helps in maintaining the consistency of the data in the spreadsheet. It controls the type of data that can enter in the data validated cells.

Data Validation in MS Excel

Now, let’s have a look at how data validation works and how to implement it in the worksheet:

To apply data validation for the cells, then follow the steps.

1: Choose to which all cells the validation of data should work.

2: Click on the DATA tab.

3: Go to the Data Validation option.

4: Choose the drop down option in it and click on the Data Validation.

Once you click on the data validation menu from the ribbon, a box appears with the list of data validation criteria, Input message and error message.

Let’s first understand, what is an input message and error message?

Once, the user clicks the cell, the input message appears in a small box near the cell.

If the user violates the condition of that particular cell, then the error message pops up in a box in the spreadsheet.

The advantage of both the messages is that the input and as well as the error message guide the user about how to fill the cells. Both the messages are customizable also.

Let us have a look at how to set it up and how it works with a sample

Data Visualization in R with ggplot2: A Beginner Tutorial

A famous general is thought to have said, “A good sketch is better than a long speech.” That advice may have come from the battlefield, but it’s applicable in lots of other areas — including data science. “Sketching” out our data by visualizing it using ggplot2 in R is more impactful than simply describing the trends we find.

This is why we visualize data. We visualize data because it’s easier to learn from something that we can see rather than read. And thankfully for data analysts and data scientists who use R, there’s a tidyverse package called ggplot2 that makes data visualization a snap!

In this blog post, we’ll learn how to take some data and produce a visualization using R. To work through it, it’s best if you already have an understanding of R programming syntax, but you don’t need to be an expert or have any prior experience working with ggplot2

Step-by-Step Tutorial: From Data Preprocessing to Using Graph Database

This article is contributed by Jiayi98, a Nebula Graph user. She shared her experience in deploying Nebula Graph offline and preprocessing a dataset provided by LDBC.

This article is contributed by Jiayi98, a Nebula Graph user. She shared her experience in deploying Nebula Graph offline and preprocessing a dataset provided by LDBC. It is a beginner-friendly step-by-step guide to learn Nebula Graph.

This is not standard stress testing, but a small-scale test. Through this test, I got familiar with the deployment of Nebula Graph, its data import tool, its graph query language, Java API, and data migration. Additionally, now I have a basic understanding of its cluster performance.

Preparation

Internet connection is necessary for the following preparations.

  1. Download an RPM file of Docker: https://docs.docker.com/engine/install/centos/#install-from-a-package
  2. Download a TAR file of Docker Compose: https://github.com/docker/compose/releases
  3. Pull the following images from https://hub.docker.com/search?q=vesoft&type=image and run docker save image name to save them to tar archives: nebula-metad, nebula-graphd, nebula-storaged, nebula-console, nebula-graph-studio, nebula-http-gateway, nebula-http-client, nginx, and nebula-importer.
  4. Copy and modify the YAML file from https://github.com/vesoft-inc/nebula-docker-compose/blob/docker-swarm/docker-stack.yaml
  5. On the nebula-graph-studio GitHub page (https://github.com/vesoft-inc/nebula-web-docker), download its RPM file.

Tutorial: Getting Started with R and RStudio

In this tutorial we’ll learn how to begin programming with R using RStudio. We’ll install R, and RStudio RStudio, an extremely popular development environment for R. We’ll learn the key RStudio features in order to start programming in R on our own.

If you already know how to use RStudio and want to learn some tips, tricks, and shortcuts, check out this Dataquest blog post.
