The solution gives the details of computing relative frequency of a given data.
The solution gives detailed steps on calculating a series of statistical questions: first setting up the frequency table, then calculating the relative frequency and cumulative relative frequency. Finally, an ogive curve accompanying to the table is drawn with explanation.
Need some direction on answering the attached questions. The questions involve tables for Frequency, Relative Frequency and Cumulative Relative Frequency and plot the Ogive curve.View Full Posting Details
