Using the skills you learned in weeks 1 and 2 evaluate a set of statistics. An Excel spreadsheet is attached including 30 data sets representing the height and weight of 14 year old boys. The first column is the height in inches and the second the weight in pounds. Choose one data set that has not already been selected (include the number of the data set in your title to make this easier to do). Calculate the mean, median and mode of the weights in the data set. You can either do this by hand or see the video below to show you how to do this using the tools in Excel. Then, explain what these numbers mean. Are they the same? Why are they different?
Then, construct a scatter plot.
From the insert menu select scatter or the chart that says scatter and then select the chart at the top left on the dropdown
Click on one of the points
Select Add Trendline (Note you may need to add Trendline and then click on the line to format Trendline)
The default radio button is linear, keep it checked
What are your observations from the scatter plot? Does it appear that there is a correlation between the height and weight of 14 yr old boys. Note: this data is made up, so do you think this is accurate? Do you think given real data that there would be a greater amount of correlation or less?
