a) true
b) false

Answer 1

Z-scores are used to indicate the central tendency of a distribution.

Step-by-step explanation:

In statistics, z-scores are used to indicate the central tendency of a distribution.

True. The standard normal distribution, also known as the z-distribution, has a mean of 0 and a standard deviation of 1. Z-scores tell us how many standard deviations a given value is from the mean, allowing for comparison of scores from different data sets. This helps determine the centrality of the distribution.
