So I have some data:
|Ball-bearing diameter (cm)||TEST 1||TEST 2||TEST 3||MEAN|
P.S with the question mark, I'm not sure what it is.
So I need to put this data on a line graph but I'm not sure how.
I also need to describe the pattern in the results.
Including your knowledge of forces (Like year 8 knowledge) to explain the patterns seen in the results.
The question mark will be the mean of the three test values, namely (5.8 + 6.2 + 7.9)/3, with the result rounded to one decimal place.
In the first instance try plotting the diameters on the x-axis and the corresponding mean values on the y axis.
