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.
