What is a symmetric histogram?
Understand the Problem
The question is asking for the definition and explanation of a symmetric histogram, which is a type of histogram where the left half is a mirror image of the right half, indicating that the data distribution is balanced around a central value.
Answer
A symmetric histogram shows a central peak with mirror image tapering on both sides.
A symmetric histogram has a prominent 'mound' in the center and shows similar tapering to the left and right, resulting in a mirror image when folded vertically. The data is usually unimodal.

More Information
Symmetric histograms often indicate that the data is normally distributed. Understanding symmetry helps in identifying the central tendency and variability in the data.
Tips
A common mistake is confusing uniform distributions with symmetric distributions. Remember, a symmetric distribution specifically has a central peak and similar tapering on both sides.
