Question 64

An agricultural scientist monitored the daily milk yield (in litres) of dairy cows from two different breeds, Breed X and Breed Y, over a lactation period. The scientist calculated the mean, median, and mode of the daily yields for each breed. The results are shown in Table 1 below.

Table 1: Measures of central tendency for daily milk yields (litres)

Measure of central tendency	Breed X	Breed Y
Mean	28.5	34.2
Median	28.5	29.8
Mode	28.5	24.0

Using the data in Table 1, explain how the distribution of daily milk yields for Breed X differs from the distribution of daily milk yields for Breed Y.
