Symmetric histogram is a graphical representation of data that is mirror-symmetrical about a vertical line. This line is typically the y-axis, but it can be x-axis if the data are reversed. The symmetry of a symmetric histogram indicates that the data are evenly distributed around the central value.
Example of Symmetric Histogram
Here is an example of a symmetric histogram:
As you can see, the left side of the histogram is a mirror image of the right side. This symmetry occurs because the data is evenly distributed around the center value. Symmetric histograms are often used to represent data that is normally distributed.
Advantages of Symmetric Histogram
There are some advantages of using a symmetric histogram when analyzing data.
- It is easier to see patterns and trends in the data when it is displayed in a symmetric histogram.
- The symmetric histogram makes it easier to compare data sets side by side.
- Itcan be used to calculate measures of central tendency, such as the mean and median, more accurately than other types of data displays.
