REWARDING THERE ARE 4 PROBLEMS BUT ONLY 3 SCREENSHOTS

#1: The whole value of data is 21.

There are 21 data values on the dot plot.

#2: The number of data values is 14.

#3: The unit is: 21 ÷ 14.

And it is 1.5.

#4: A statistical question can be answered by collecting data and where there will be variability in that data.

For example, how many students enjoy playing game?

Your answer would be C. 1/2.

The difference between each y-coordinate is 1 and the difference between each x-coordinate is 2, creating the slope 1/2 from each point.

Hope this helps :)
