Question: Which of the following statement(s) is/are true? I. On a pareto chart, the frequencies should be represented on the y - axis. II. In a frequency distribution, the number of classes should be between 5 and 20. III. The three types of frequency distributions are histograms, frequency polygons and ogives. A ) I and II only B ) II only C ) III only D ) all are true Steps to derive 1 On a pareto chart, the qualitative or categorical data is represented on the x - axis and frequencies are represented on the y - axis.2 In a frequency distribution, there should be between 5 and 20 classes. Although there is no hard-and-fast rule for the number of classes contained in a frequency distribution, it is of the atmost importance to have enough classes to present a clear description of the collected data.3 The three types of frequency distributions are the categorical frequency distribution, the grouped frequency distribution and the ungrouped frequency distribution.4 So, only statements I and II are true.Hence the right answer is Option A Click Here To Go Back Few Other Questions - Between which two consecutive integers does 173 lie?..
