The median is the middle value in an ordered set of data.First, get the sum of the Frequency column.Score (x) Frequency (f) Cumulative Frequency 5 4 6 8 7 10 8 6 9 3 10 2 Total=33 To find the median, fill in the Cumulative Frequency column by adding the frequency, as seen below.Score (x) Frequency (f) Cumulative Frequency 5 4 4 6 8 4+8=12 7 10 12+10=22 8 6 22+6=28 9 3 28+3=31 10 2 31+2=33 Total=33 To check, the last entry in the Cumulative Frequency column must be equal to the
Total Frequency.Since the total number of scores is 33, the middle score should be the 17th score.Find the row that includes the 17th score.Score (x) Frequency (f) Cumulative Frequency 5 4 4 6 8 4+8=12 7 10 12+10=22 8 6 22+6=28 9 3 28+3=31 10 2 31+2=33 Total=33 The third row covers all scores between the 12th and 22nd position — this includes the 17th.Hence, the median is 7.Median=7 -

Incorrect
The median is the middle value in an ordered set of data.Find the middle value in the cumulative frequency axis (left side).Since the highest value is 25, simply divide it by 2.252 = 12.5 Trace a horizontal line from 12.5 until it touches part of the polygon.Notice that it touches the polygon across the bar for the score 3.Hence, the median is 3.Median=3 -
