A scientific look at the efficiency of curling brooms by Jenni Gill
These graphs are compiled use the data that was collected during testing. The graphs are interactive and dragging your curser over a point will give you more information on that specific data point. Clicking on a section of the legend will turn off the corresponding data points, clicking it again will turn the points back on.
The equation I used for the average of the control was (one control rock + the next control rock)/2. I used the same equation for the average of the control on the.
I did this to be able to compare the swept rock to what an unswept rock would have done.

The equation is all of the distances form one type of broom/ number of distances. This shows how far the rock swept by each type of broom traveled on average. The red is the same thing only without the two highest and two lowest form the swept rocks and the four highest and lowest from the controls.
The equation is (swept rock - control rock) x 100/ the average of the control. This graph shows, as a percentage, how much further the unswept rock went than the unswept rock.
Sorted the data from % differences to show them in order form lowest to highest instead of chronological order. The way I interpreted the graph is to ignore the outliers which are the two highest and two lowest points on each line. The middle points are the averages for each broom.
