Initial analysis of the data needs to be performed to determine the distribution to use for analysis of the data.

Histogram of the data to view the general shape to get an indication of what type of distribution to use for analysis.

1. Generate a histogram of the data.

2. Does it look like it might be lognormal?

3. Does the histogram look reasonably normal? 4. What is the mean of the distribution?

5. What is the Standard deviation?
