Box and Whiskers Videos

What is the purpose of a box and whisker plot?

• To measure the data's standard deviation

• To find the exact value of each data point

• To visualize data distribution and range

• To calculate the average of a data set

Why is it important to rearrange data from least to greatest when creating a box and whisker plot?

• To find the median more easily

• To calculate the total sum of the data

• To identify duplicate values

• To determine the mode of the data set

What does the upper extreme represent in a box and whisker plot?

• The lowest value in the data set

• The median value

• The highest value in the data set

• The average value

How is the median value found in a data set?

• By finding the value in the middle of the data set

• By adding all the numbers and dividing by the total count

• By calculating the difference between the highest and lowest values

• By averaging the two most common numbers

What does the interquartile range represent?

• The range between the upper and lower extremes

• The range between the upper and lower quartiles

• The range between the median and the upper extreme

• The total range of the data set

What can a coach infer about a player's performance from the box and whisker plot?

• The player's exact scores in each game

• The player's preference for playing position

• The player's scoring consistency

• The player's potential for improvement

What does the lower extreme indicate in a box and whisker plot?

• The second lowest value in the data set

• The median of the lower half

• The average of all data points

• The lowest value in the data set

What is the median value in Jess's coffee shop data?

• 55

• 51

• 96

• 59

How do you find the upper quartile in a data set?

• By finding the median of the upper half of the data

• By doubling the median value

• By averaging the two highest values

• By subtracting the lower quartile from the median

What is the final step in constructing a box and whisker plot?

• Calculating the interquartile range

• Marking the data points on the number line

• Drawing horizontal lines to connect quartiles to extremes

• Drawing the median line
