We will use the StatDisk. Go towww.statdisk.comand open a fresh spreadsheet.

For scatter plots, enter Age in Column 1 and Vocabulary in Column 2 and generate a scatter plot. Go to the Data drop-down menu and select "Scatter Plot." The x-value should be the explanatory variable and y-value should be the response variable.

Be sure to label the x and y axis, and then generate a scatter plot and cut and paste it into this document. Use the StatDisk scatterplot displayed to answer the following questions.

Use the following data set to answer the questions about correlation.

The table shows the Age and Vocabulary Size. Researchers examined data from 11 different children between the ages of 1 and 6.

Age 1 2 3 4 5 6 3 5 2 4 6

Vocab 3 440 1200 1500 2100 2600 1100 2000 500 1525 2500

Size

1. Answer this preliminary question before you start:Do you think that there is a relationship between age and vocabulary size?

2. Scatter Plots

a. Who are the individuals in this study? b. What is the explanatory variable? c. What is the response variable? d. Make a scatter plot where the x-axis shows the explanatory variable, and the y-axis

shows the response variable. e. Describe the form, direction, and strength of the relationship?
