Unit 5 - Statistics

Overview

For the rest of the school year, we will be learning the basics about statistics. We will talk about the main ways data is displayed, and how we can make comparisons and draw conclusions based on what we see.

Topic 1 - One Variable Statistics

For 1-variable statistics, we will be collecting single data sets. For example, you could ask everyone in the class one question:

• What is your height?
• What is your shoe size?
• What is your age?
• When is your birthday?
• How many hours do you play Fortnite per week?

Or you could take any number of measurements/data from the real world. Once you have data, you will display them one of three ways. (See below). Then you will use the graphs and measures of center (mean and median) to summarize and compare the data.

Topic 2 - Two Variable Statistics

For 2-variable statistics, we will be collecting two sets of data at a time that we think are related (i.e. I think that gaming more might cause you to get less sleep, so I might survey students about how many hours they spend gaming and how many hours of sleep they get per night). For example, you could ask everyone in the class:

• What is your height and shoe size?
• How many hours do you spend on Fortnite per week? What % do you have in math class?
• How many hours of sleep do you get? How many hours per day do you game?
• How many days do you eat out per month? How many minutes of exercise do you get per month?

Or again, just find any two data sets that you think are related from the real world. Once you have data, you will display them as a scatter plot and try to determine whether the line of best fit is linear, quadratic, or exponential. You will use Desmos to calculate the line of best fit. Then, you will interpret that equation and use it to predict new information.
