11.5 Finding Raw Scores from Probabilities
The function NORM.INV(probability,mean,standard_dev)
, where probability is in the percentage form, will provide the raw value corresponding to the probability (or percentile).
- Select cell M1 and type the label 90th Percentile.
- In cell M2, type the label 95th Percentile.
- In cell M3, type the label 99th Percentile.
- In cell N1, type
= NORM.INV(90%, $H$2,$H$4)
.
Note: Remember to include the $
symbol.
- Repeat Step 4 above to obtain the other percentiles, 95th in cell N2 and 99th in cell N3.
