The document describes a Squawka Academy session that teaches students how to analyze football player statistics. It discusses analyzing the shot conversion percentage and pass completion percentage of 10 strikers. Students are asked to plot a scatter graph of goals vs shots, draw a line of best fit, and identify the 2 best and 2 worst strikers based on their position relative to the line. In groups, students then use the stats to pick the best striker and present their analysis, with the chance to win a prize for the best presentation.

Remember, we are not using the INTEGER, but the
DECIMAL VALUE
25 Percentile = ((n+1)/4)th = 2.75th Value = 422.25
75 Percentile = ((n+1)/4) x 3)th = 8.25th Value = 998
IQR = 998 - 422.25 = 575.75

Two Best: Berbatov, Benteke (Below the line = Fewer Shots, More Goals) Argument for
Van Persie too, but closer to line.
Two Worst: Carroll, Tevez (Above the line = More Shots, Fewer Goals) Also Suarez, but did
score 23 goals.
