So I have some data:

Ball-bearing diameter (cm) TEST 1 TEST 2 TEST 3 MEAN
1.4 2.1 2.0 1.9 2.0
1.6 2.9 3.0 3.0 3.0
1.8 5.8 6.2 7.9 ?
2.0 11.1 11.3 11.1 11.2
2.2 19.7 19.8 20.0 19.8

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.
