The weights of hummingbirds are given below in ounces. Show whether the mean or the median is a better choice for a “typical” hummingbird’s weight and calculate it.

Data in order : 4, 5, 7, 8, 8, 9, 9, 9, 9, 10, 10, 10, 10, 10, 10, 10, 11, 11, 11

Respuesta :

Since the data-set contains outliers, the median is a better choice, and it is given of 10 ounces.

When to use the mean or the median?

It depends if the data-set contains outliers or not.

  • If it does, the median should be used.
  • Otherwise, the mean should be used.

In this problem, the weights of 4 and 5 ounces are outliers, hence the median should be used. There are 19 values, hence the median will be given by the 10th value, which is 10. Hence the median is of 10 ounces.
