Question 5 of 7
5. Question
The box and whisker plot below represents the number of goals scored per month by a soccer team. Find the range.
 `\text(Range )=` (10)
Correct
Keep Going!
Incorrect
Range Formula
`color(deeppink)(\text(Highest Score)) – color(darkviolet)(\text(Lowest Score))`Remember
A boxandwhisker plot shows a fivepoint summary of the lowest score, lower quartile, median, upper quartile and highest score.The lowest and highest scores are indicated by the whiskers of the box and whisker plot`\text(Highest Score)` `=` `12` `\text(Lowest Score)` `=` `2` Subtract the lowest score from the highest score to get the range`\text(Range)` `=` `color(deeppink)(\text(Highest Score)) – color(darkviolet)(\text(Lowest Score))` Finding the range `=` `color(deeppink)(12)color(darkviolet)(2)` Substitute values `=` `10` Evaluate `\text(Range)=10`

Incorrect
Interquartile Range
`\text(IQR )=color(deeppink)(\text(Q)_\text(Upper))color(darkviolet)(\text(Q)_\text(Lower))`Remember
A boxandwhisker plot shows a fivepoint summary of the lowest score, lower quartile, median, upper quartile and highest score.The lower and upper quartiles are indicated by the outer lines of the box and whisker plot`\text(Upper Quartile)` `=` `18` `\text(Lower Quartile)` `=` `14.5` Use the formula to get the interquartile range.`\text(IQR)` `=` `color(deeppink)(\text(Q)_\text(Upper))color(darkviolet)(\text(Q)_\text(Lower))` Interquartile Range formula `=` `color(deeppink)(18)color(darkviolet)(14.5)` Substitute values `=` `3.5` Evaluate `\text(IQR)=3.5` 
Question 7 of 7
7. Question
The box and whisker plot below represents the number of goals scored per month by a soccer team. Find the median.
 `\text(Median )=` (6)
Correct

Incorrect
The median is the middle score in a data set.A boxandwhisker plot shows a fivepoint summary of the lowest score, lower quartile, median, upper quartile and highest score.The median is indicated by the line inside the box and whisker plotThe line inside the box points to the score `color(tomato)(6)` on the number line.Therefore, the median of the box and whisker plot is `6`.`\text(Median)=6`
