2. Work out the Inter-Quartile Range of the Completed Passes column for
the 10 players. Use exact, do not round up! Comment on the findings
3. On the graph paper provided:
a) Plot a scatter graph of goals against shots for all 10 strikers
b) Draw a Line of Best Fit & make an estimate of its Equation
c) Comment on who you think are the 2 best and 2 worst strikers based on
what players are above and below the line

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.
