Determine the classes: For quantitative data, we need to define the classes first. There are 3 steps to define the classes for a frequency distribution: Step 1: Determine the number of nonoverlapping classes, usually 5 to 20 classes. Step 2: Determine the width of each class,

1The signal has to be stationary, which means that us statistics do not change as a function of time. ( If a random signal x(t) is passed through a time-invariant filter with frequency response H(f), the resulting signal y(t) has a PSD as follows: Example: Random Gaussian noise signals.

Draw a frequency polygon of these data. Draw a dot plot of these data. Draw a pie chart based upon the frequency table’s classes. (Yes, you can use a pie chart for GROUPED quantitative data.) Show slice size calculations. Build a double Stem-and-Leaf plot of the data. Determine the mean, median, mode and midrange for these data.
