(f) The researcher notices that the industry standard software package entry for the ninth test was a typing error. The correct value should have been 434. The revised mean and median for the industry standard software package data with the correct value for the ninth test are given in the following table. Industry standard software package Mean Median With typing err error With correct value 464.4 454.4 464.5 459.5 What is the effect on the mean and on the median of including the typing error instead of the correct value? Explain why this happens. (g) Would having the correct value affect the researcher's conclusion in part (e)(i)? Explain your answer briefly. page 5 of 7 [2] [2] Number of minutes to complete the test Industry standard In-house Minimum (Min) Lower quartile (Q1) 438.5 419.5 Median 464.5 429.5 Upper quartile (Q3) 481.5 438.5 Maximum (Max) Mean 464.4 428.95 Standard deviation (SD) 48.22 12.13 Interquartile range (IQR) Range Size of dataset (n) 20 20 (f) The researcher notices that the industry standard software package entry for the ninth test was a typing error.
