# Algebra Course: Introduction to Statistics

This video tutorial provides a basic introduction into statistics.  It explains how to find the mean, median, mode, and range of a data set.  It also explains how to find the interquartile range, quartiles, percentiles as well as any outliers.  The full version of this video which can be found on my patreon page also mentions how to construct box and whisker plots, histograms, frequency tables, frequency distribution tables, dot plots, and stem and leaf plots.  It also covers relative frequency and cumulative relative frequency as well as how to use it to determine the value that a corresponds to a certain percentile.  Finally, this video also discusses skewness - it explains which distribution is symmetric and which is skewed to the right (positive skew) and which is skewed to the left (negative skew).

## Course Review: Python for Linear Algebra

Because I am continuously endeavouring to improve my knowledge and skill of the Python programming language, I decided to take some free courses in an attempt to improve upon my knowledge base. I found one such course on linear algebra, which I found on YouTube. I decided to watch the video and undertake the course work because it focused on the Python programming language, something that I wanted to improve my skill in. Youtube video this course review was taken from:- (4) Python for linear algebra (for absolute beginners) — YouTube

The course is for absolute beginners, which is good because I have never studied linear algebra and had no idea what the terms I would be working with were.

Linear algebra is the branch of mathematics concerning linear equations, such as linear maps and their representations in vector spaces and through matrices. Linear algebra is central to almost all areas of mathematics.

Whilst studying linear algebra, I have learned a few topics that I had not previously known. For example:-

A scalar is simply a number, being an integer or a float. Scalers are convenient in applications that don’t need to be concerned with all the ways that data can be represented in a computer.

A vector is a one dimensional array of numbers. The difference between a vector is that it is mutable, being known as dynamic arrays.

A matrix is similar to a two dimensional rectangular array of data stored in rows and columns. The data stored in the matrix can be strings, numbers, etcetera.

In addition to the basic components of linear algebra, being a scalar, vector and matrix, there are several ways the vectors and matrix can be manipulated to make it suitable for machine learning.

I used Google Colab to code the programming examples and the assignments that were given in the 1 hour 51 minute video. It took a while to get into writing the code of the various subjects that were studied because, as the video stated, it is a course for absolute beginners.

The two main libraries that were used for this course were numpy and matplotlib. Numpy is the library that is used to carry out algebraic operations and matplotlib is used to graphically plot the points that are created in the program.

## Leadership Courses | Learn How to Speak Like a Leader | Simpliv

Description
Imagine that every time you speak, people perceive you as a confident and authoritative leader. Wouldn’t it be nice to know that you can speak in a confident manner and in a way that is instantly understandable and memorable to your audience?

In this How to Speak Like a Leader course you will learn the following:

How to avid the most common speaking blunders that undermine authority
How to increase eye contact with your audience
How to structure your presentation so that you don’t seem like a mid-level bureaucrat
How to prepare in the least amount of time possible
This course is delivered primarily through spoken lecture. Because the skill you are learning is speaking related, it only makes sense that you learn through speaking.

The skill you will learn in this class is not primarily theoretical or academic. It is a skill that requires physical habits. That is why you will be asked to take part in numerous exercises where you record yourself speaking on video, and then watching yourself. Learning presentation skills is like learning how to ride a bicycle. You simply have to do it numerous times and work past the wobbling and falling off parts until you get it right.

This course contain numerous video lectures plus several bonus books for your training library.

TJ Walker has been coaching and training people on their presentation skills for 30 years. Now, through the power of Simpliv’s online platform, he is able to give you the same high quality training that he gives in person to CEOs, Fortune 500 executives, and Presidents of countries. Only you can now receive the training at a tiny fraction of the normal fee for in-person training.

How long this course takes is up to you. The longest part of the course involves you speaking on video, critiquing yourself, and doing it over until you like it. But if you get to the point where you love how you look and sound when you present it will be well worth the time spent. And having this skill will save you time for all future presentations in your life.

You can begin improving your leadership presentation skills right now. You may have an opportunity to speak out as soon as tomorrow, so why waste another day worried that your presentation skills are not up to high standards. Enroll in this course today.

There is a 100% Money-Back Guarantee for this course. And the instructor also provides an enhanced guarantee.
