Question

A track coach records three sprinters' statistics throughout the season. The median 400-meter race time, in seconds, and the interquartile range, IQR, for each athlete are recorded in the table below. Athlete A Athlete B Athlete C Median = 63 IQR = 3 Median = 61 IQR = 2 Median = 59 IQR = 4 Use the information in the table to complete the following statement. Athlete shows the most consistency in her 400-meter race time, because her is the .

Answer 1

Athlete B shows the most consistency in her 400-meter race time, because her interquartile range is the lowest

Explanation:

Hope this helps :)

Answer 2

B Athlete Median = 61 IQR = 2 athlete shows the most consistency in her 400- meter race because her Interquartile range variability is less compare to the others.

Explanation:

• Median is the mid-point of the data.
• Median takes average of 25%, 50%(Median) and 75% of data.
• Box plot is an easier way to understand Mean and Median.
• Interquartile range helps in finding the variability.
• Q3(Third quartile) - Q1(First quartile) gives variability.
• The IQR number is higher it is high variability.
• Median comes in descriptive statistics, It helps in describing data.
• Median helps in finding the outliers and skewness of the data.
