Represent the frequency on Y- axisStep 4: Place bars (rectangles) adjacent to each other as well as separated from each other such that the height of bars represent the frequencies of the respective observations. Inferential Statistics, is concerned with inferring or drawing conclusions about the population based on pre selected elements of population. The cumulative frequency distribution
is a table that gives the cumulative frequencies against some x values
(for us the class boundaries). Appendix B includes descriptions of the 32 data sets that can be downloaded from the companion website www. Easily read eBooks on smart phones, computers, or any eBook readers, including Kindle. Example 1: Find the mean of the data.
