Scroll down to find Q1 and Q3…� Q1 = 12.3 and Q3 = 12.7

5 of 6

Scroll down to find Q1 and Q3…� Q1 = 12.3 and Q3 = 12.7

IQR = Q3 – Q1 = 0.4��Outliers:�Q1 – 1.5(0.4) = 12.3 – 0.6 = 11.7�Q3 + 1.5(0.4) = 12.7 + 0.6 = 13.3

Therefore, 10.8 is an outlier as it lies below 11.7

With the point (6, 10.8)�removed from the data table, �the new r-value is :

r = -0.86

Shows a strong correlation.��Line of best fit:�y = -0.06x + 12.93
