If you're interested in Data Visualization then you've come to the right place. Ggplot (or ggplot2) is an extremely powerful package used in R programming to develop plots and graphs. A lollipop graph is an excellent example of how you...

If you're interested in data visualization or creating plots and graphs using ggplot then you really need to get into using colors effectively. Most people who use R programming to create graphics use the package ggplot2 and the...

If you're using R programming for data visualization then you're going to love this video. Creating plots and graphs using ggplot2 couldn't be easier. Ggplot using a concept called geoms (or geometries) to determine the type of plot that...

If you're using R programming to do data visualization using ggplot2, then you'll love this video. Greg Martin walks you through the process of creating error bars on your plots and graphs. This can be used for bar charts, scatter plots,...

If you are doing data visualisation with ggplot the you'll find this video useful. ggplot2 is one of the tidyverse packages and is used to create graphs and plots. Data visualization is an important part of both understanding and...

If you are learning to work with data then being able to structure, manipulate and summarize your data is extremely important. This forms part of what we call descriptive statistics. the group_by() and summarise() functions are part of...

If you're learning about statistical analysis using R programming then you'll love this video. In it Dr Martin explains how to use R studio and R programming to do a chi-squared test to compare proportions of a categorical variable. This...

Adding polynomial functions produces another polynomial function. The values of this function are the sum of the values of the polynomials that were added for every possible value of the input variable(s). Fortunately, adding polynomial...

"Pythagorean Theorem" will show that the area of two squares (sides A and B) equals the area of square (side C).

The video “Simplify Expressions” introduces algebra tiles as a helpful tool for representing and simplifying algebraic expressions.

Evaluate algebraic expressions by substituting a value for the variable in an expression.

Equations with Fractions demonstrates how to solve one-step equations by using reciprocals when the coefficient of the variable is a fraction.
