Question

#40 what do we call a data set where the left half of the histogram is a mirror image of the right half of the histogram? (a) skewed (b) symmetric (c) bell - shaped (d) uniform (e) none of these

Explanation:

A symmetric dataset has a histogram where the left - hand side is a mirror image of the right - hand side. A skewed dataset is not symmetric. A bell - shaped distribution is a type of symmetric distribution, but the general term for a dataset with mirror - image halves is symmetric. A uniform distribution has all values occurring with equal frequency and may or may not be symmetric in the mirror - image sense described.

Answer:

B. symmetric
