Question

explain how to determine the skewness using a frequency curve​

Answer 1

Answer:

It is also called asymmetrical distribution. For this type of frequency distribution mean, median and mode do not have same value (Fig. 5.8 (b) and (c)). Skewness is + ve or — ve depending upon location of the mode with respect to the mean.

Shape of Frequency Curves

In a positively skewed distribution there is a long tail on the right and the mean is on the right of the mode (Fig. 5.8 (b)).
