# Frequency Distribution Analysis and Calculations

Please see the attached file for the complete problem description.

1. Prepare a frequency distribution of ungrouped data including cumulative frequency (tally) for the table of approved

2. Calculate the mean, mode and median of the table of approved

3. Calculate the range, variance and standard deviation table Approvals

4. Prepare a distribution of pooled data for table height must use five intervals

5. Prepare a bar graph (histogram) of this distribution.

#### Solution Preview

Please see the attached file for a complete step by step explanation of how to solve this question.

1. Prepare a frequency distribution of ungrouped data including cumulative frequency (tally) for the table of approved

First of all we need to put the data in ascending order (from smallest to largest) in this way we can see more clearly which numbers appear more than once

Table 1

(please see the attached file)

Now we count how many times each number ...

#### Solution Summary

This solution provides a step by step calculation of all basic (descriptive) statistics from both the ungrouped and grouped (pooled) data.
