If you were going to gather some statistics to create a scatter plot, draw a line of best fit, and interpret the slope and y-intercept in context, which of these would be a good statistical question to ask? Check all that apply.
1Was your height greater than 60 cm before your last birthday?
Was your height greater than 60 cm before your last birthday?
2What kind of car does your family drive?
What kind of car does your family drive?

5How tall are the students in your grade level at school?
How tall are the students in your grade level at school?
6What is your favorite color?
3, 4, 5
The following questions would be good for gathering statistics, creating a scatter plot, drawing a line of best fit, and interpreting the slope and y-intercept in context:
3) What percentage of families in Florida had a radio in 1930?
4) How is college student enrollment changing over the last century?
5) How tall are the students in your grade level at school?
The following questions would be good statistical questions to gather data for creating a scatter plot, drawing a line of best fit, and interpreting the slope and y-intercept:
3) What percentage of families in Florida had a radio in 1930?
4) How is college student enrollment changing over the last century?
5) How tall are the students in your grade level at school?
These questions involve variables that can be measured or quantified, which is essential for creating a scatter plot. The first two questions, however, would not be appropriate as they do not provide numerical data that can be plotted on a scatter plot. The last question about a favorite color is based on personal preference and cannot be easily represented as numerical data.
