Develop a relative frequency distribution and a percent frequency distribution C. Lastly, present the quantitative data using Histogram (Open Data Analysis)One of the primary goals of constructing a frequency distribution for quantitative data is to summarize the data O by showing frequency of values that lie within a class or bin. O so that there are always 7 classes or bins of data. O ensuring that the classes or bins are always of different widths. O in a manner so that each class or bin has the same number of data points.
