Please answer letter d, B, and C. A. Develop a Frequency Distribution using 5 Classes a. Establish 5 classes for the entire range of data b. Compute for the Approximate Class Width c. Determine the Lower and Upper Class Limits for each Class d. Use the Frequency Function to automate Count =FREQUENCY(data array, bins array) B. 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.
