ok so I did a radiation and distance lab: this is my results:

Distance(cm) Counts(30 sec)
0 1729
1 634
2 391
3 239
4 150
5 124
6 114
7 82
8 58
9 62
10 60
11 36
12 45

so it asks me to make new columns on excel titled the following:(note: the 2 and 3 are superscripts)

1/distance
1/(distance)2
1/(distance)3

then it says to plot radiation counts versus each of these. ^(aka the ones above)keep the ones that give the best straight line.

I have no idea what it is telling me to do when it says "plot radiation counts versus each of these. ^"

can someone please help me? thanks;)

oops the numbers after the 1,2,3 etc. are suppose to be in the right column
