This instructional video reviews how a scatterplot is used to determine a relationship between two variables. The video reviews how a two variable data set can also be displayed using circle graphs and double bar graphs. Three different scatterplots show the three kinds of relationships that potentially exist with two variables: positive, negative, and no relationship. The possibility of outliers is also addressed. Like my other instructional math videos, music and gifs help to make the mate
This video reviews the mean, median, and mode and how to calculate these averages. Further, this video goes over why each of these types of averages are used based on the question that is given. Reference is made to how an outlier can skew a data set, making the mean not the most reliable way to calculate an overall average. As with other videos in my distance learning series, GIFs and music are used to make the content more engaging for students.
