Question & Answer
The distribution of pH levels of the water samples is best described as _______________. So, the mean ________________ an appropriate measure of center.
1 Answer
Verified archiveThe correct answer is 3. skewed; is.
Explanation: If the pH levels of the water samples are not evenly distributed and tend to cluster towards one end of the scale, they can be described as “skewed.” In such cases, the mean is considered an appropriate measure of center because it takes into account all values in the dataset. If the distribution were symmetrical, other measures like the median might be more appropriate, but skewed distributions allow for the mean to provide a useful summary of the data.
