Question

For the past 100 years, the mean bạtting average in the major leagues has remained fairly constant at about 0.244. However, the standard deviation of batting averages has decreased from about 0.046 in the 1910s to 0.032 at present. What does this tell us about the batting averages of players?

Answer 1

The standard deviation tells us how concentrated the data are around the mean. They could be close or far away from the mean. A smaller standard deviation means that the data are closer to the mean.

Looking at the given scenario, the average or mean is 0.244. The standard deviation has decreased from about 0.046 to 0.032.

This means that the batting averages of players are getting closer to the mean of 0.244.
