# Probability Distribution of Data

Paper instructions:

Assignment

1. You are asked to take readings to create a sample of 50 measurements of flow rate (Q).

2. Perform the following analysis

Analysis

1. Calculate sample statistics i.e., mean and standard deviation (precision index) for the sample

2. Determine whether the flow rate sample follows normal distribution by

a. Skewness and Kurtosis analyses

b. Histogram and frequency analysis

c. Plotting data on a normal probability paper

i. While you plot data on normal probability paper estimate mean and standard deviation from the plot as well.

d. P-P plot

3. Compare your findings from each of the analyses and comment

4. How do your estimated mean and standard deviation from
