Question
Here's some raw data for a made up place, and I need to know how to find the rainfall intensity. The teacher posted answers, I just can't follow how arrived at the answer
These are the maximal annual precipitation amounts of the 2 hour events in some place I made up:
0.833093
0.633898
0.803696
0.622954
0.998817
0.128545
0.958072
0.689343
0.647056
0.14525
0.601227
0.870724
0.351631
0.186481
0.928724
0.189343
0.906004
0.173238
0.314116
0.802034
0.155463
0.104216
0.984582
0.856214
What is the 5 years 2 hour precipitation intensity?
ANSWER:
T=(n+1)/rank rank=(n+1)/T=(24+1)/5=5
i5(rank 5)= 0.906004
0.833093
0.633898
0.803696
0.622954
0.998817
0.128545
0.958072
0.689343
0.647056
0.14525

0.314116
0.802034
0.155463
0.104216
0.984582
0.856214
Explanation / Answer
first arrange the whole rainfalls in decending orders because you are asked maximal annual precipitation
than use the formula rank=(n+1)/T
here your time is 5 years as given in question
now after calculation you will get 5 as rank now
now look down the table and choose the 5th one
this is the required precipitation 0.906004
