Perfect distribution with only one peak. Skewness coefficient equal = 0 because the mean equals to the median. Mean=Median= Mode. Skewness = (Mean-Median )/Standard deviation. Left half of the graph is a mirror of the right half of the graph.

**1-Frequency polygons**

Looks like a line graph. You make a dot for each observation. Class midpoint on **x-axis** and frequency on** y-axis**. Drawn over a histogram. The **midpoint** of a bin is calculated by adding the upper and lower boundary values of the bin and dividing the sum by 2.
