Unit 9: Descriptive Statistics Representing Univariate Data Analyzing Univariate Data Representing Bivariate Data Analyzing Bivariate Data Functions of Best Fit Two-Way Tables 9.1 Representing Univariate Data Data, data, data! What can we do with data? Most mathematics in real life comes down to gathering and analyzing data. Hence NASA, the Hadron Collider, and most other scientific exploration decides what is most likely true based on data gathered. In this unit, we’ll be analyzing data both univariate data, which means data gathered about one variable like how many cups you can stack on top of your head, and bivariate data, which means data gathered about two variables like how many ping pong balls you can accurately throw in a bucket over different distances. Our starting point is gathering and representing the univariate data. Frequency Graphs Let’s say a class of students tried to stack as many blocks on their head as they could (without them falling off) in a minute. The table below shows the result of that experiment.
