Class 7 (Oct. 14)

There wasn’t an actual class session this week. Instead, there was a recorded lesson about hypothesis testing.

I began experimenting with the UC Berkeley Video Game Survey data and have found some interesting observations. There are less than 100 observations with most of them not liking or playing video games, causing some of the observations to have a value of 99 in some of the variables, meaning that no data was collected on that variable from the observation. In the additional data, the value NA is used instead and I need to figure out how to combine those two datasets together.

I have also experimented with making graphs with Exploratory Data Analysis through R. While I have made some graphs, I’m not sure yet how helpful some of them will be. Formatting is also an issue where it’s difficult to combine certain graphs sometimes. The value 99 is also a problem because I’m not sure if it should be removed or not.

For this and next week, I’ll continue to experiment with the dataset and learn how to use ggplot2 to make better plots in R.

Thank you for reading!
