Overview
Unit 3 builds on the concepts covered in Units 1 and 2. In Unit 3, you explore the statistics frequently used to describe data that have not yet been introduced in this course. Descriptive statistics include measures of center, mean, median, and mode; and measures of dispersion, range, variance, and standard deviation. In addition, you are introduced to probability and discrete probability distributions.
- Open the Heart Rate Excel Data Set
- Sort the quantitative variables by class (e.g., Male at-rest heart rate and Female at-rest heart rate)
- Use the Excel Data Analysis ToolPak* tools to calculate each of the following statistics:
- Mean of each quantitative variable
- Sample variance of each quantitative variable
- Sample standard deviation of each quantitative variable
- Create a table in Excel that summarizes the statistics for each variable.
- Transfer your summary results to Word.
- Interpret what the mean and standard deviation specifically tell you about the heart rates of males and females in the sample. Are the heart rates for males or females higher? Which data is more spread out and which is closest to the overall mean rate? Explain your responses.
In the topic "Measures of Center", you were provided directions on how to upload the Data Analysis ToolPak to Excel. If you have not yet uploaded the add-in Data Analysis ToolPak, please view the appropriate video and follow the instructions. You will not be able to complete this assignment without that add-in.
