Nice Job!
Incorrect
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 `\text(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 `\text(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 `17`th score.Find the row that includes the `17`th 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 `\text(Total)=33` The third row covers all scores between the `12`th and `22`nd position — this includes the `17`th.Hence, the median is `7`.`\text(Median)=7` -
Question 2 of 8
2. Question
Use this cumulative frequency histogram to find the median.
Rankings of a TV show
- `\text(Median )=` (3)
Correct

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`.`25/2` `=` `12.5` Trace a horizontal line from `color(darkgoldenrod)(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`.`\text(Median)=3` -

Correct
Nice Job!
Incorrect
The median is the middle value in an ordered set of data.Since the total number of scores is `11`, the middle score should be the `6`th score.Find the row that includes the `6`th score.Game `(x)` Frequency `(f)` Cumulative Frequency 7 4 4 8 2 6 9 3 9 10 2 11 The second row covers all scores between the `5`th and `6`th position — this includes the `6`th.Hence, the median is `8`.`\text(Median)=8` -

Incorrect
The median is the middle value in an ordered set of data.Since the total number of scores is `10`, the middle score should be the average of the `5`th and
`6`th scores.Find the row that includes the `5`th and `6`th scores.Game `(x)` Frequency `(f)` Cumulative Frequency 12 1 1 13 2 3 16 2 5 17 4 9 22 1 10 The third row covers all scores between the `4`th and `5`th position and the fourth row covers all scores between the `6`th and `9`th position.Get the average of the two scores to get the median.`\text(Median)` `=` `(16+17)/2` `=` `33/2` `=` `16.5` `\text(Median)=16.5` -

5. Question
Use this cumulative frequency histogram to find the median.

- `\text(Median )=` (4)
Correct

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 `40`, simply divide it by `2`.`40/2` `=` `20` Trace a horizontal line from `color(darkgoldenrod)(20)` until it touches part of the polygon.
Notice that it touches the polygon across the bar for the score `4`.Hence, the median is `4`.`\text(Median)=4` -

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 `35`, simply divide it by `2`.`35/2` `=` `17.5` Trace a horizontal line from `color(darkgoldenrod)(17.5)` until it touches part of the polygon.
Notice that it touches the polygon across the bar for the score `102`.Hence, the median is `102`.`\text(Median)=102`
