Section 2.1 Objectives Construct frequency distributions Construct frequency histograms, relative frequency histograms, and ogives

What is Cumulative Frequency in statistics If the frequency of first class interval is added to the frequency of second class and this sum is added to third class and so on then frequencies so obtained are known as Cumulative Frequency (c.f.). There are two types of cumulative frequencies (a) less than, (b) greater than […]

The table below shows the frequency distribution, the relative frequency, and the percentage distribution for the data set above.

A short description of key statistical terms is given in this post. The following terms are presented: frequency distributions, histograms, normal distribution, skew, kurtosis, standard deviation, standard normal distribution, z-scores, positively skewed distributions, negatively skewed distributions
