2 cards from this section. Quick, good the night before a test.
What does the Log Pearson Type III distribution help to analyze?
Think about what kind of data we are often concerned with in hydrology.
What is the formula for calculating the return period?
Recall the variables involved in the return period formula.
What is the Log Pearson Type III distribution primarily used for?
Think about extreme weather events.
True or False: The return period is calculated by T = (n + 1)/m.
Recall the return period formula we discussed earlier.
A region has recorded the following rainfall amounts (in mm): 200, 150, 300, 100, 350, 500, 250. How would you use the Log Pearson Type III distribution to estimate the return period for the maximum rainfall amount?
Ensure you first rank the data correctly and apply the formula.
Describe how varying skewness in rainfall data can impact the predictions made using the Log Pearson Type III distribution.
Reflect on how 'normal' distribution does not always apply in real life.
