Graph 3 represents the left skewed as the data set are dense on the left side.
Further explanation:
Explanation:
Dot plot is a chart in which frequency and the number can be expressed by a line and the frequency is represented by the dot.
It is a simple type of histogram. It can only be used for discrete numbers.
Skewness is a asymmetry in a normal distribution curve or in the data set. The tail of the curve may shift to the left or right.
If the tail of the curve shift left then it said to be left skewed.
If the tail of the curve shifts right then it said to be right skewed.
If the mean is greater than the median then it is said to be right skewed.
If the median is greater than the mean then it is said to be left skewed.
Graph 1 represents the right skewed as the data set are dense at the right.
Graph 2 represents the symmetrical.
Graph 3 represents the left skewed as the data set are dense on the left side.
Graph 4 doesn’t represents the right skewed, left skewed or symmetrical.
