Find Percentile with Mean and Standard Deviation (Normal Curves) | Statistics

We go over how to find percentiles with mean and standard deviation for a normal distribution, using a calculator (similar to TI-83) and a standard normal table. We discuss two problems, one where we are given a value and asked to calculate its percentile, and another where we are given a percentile and asked to calculate the corresponding value. #Statistics #APStatistics
To calculate percentiles, we need little more than a good understanding of standardized values, also known as z-scores.

Thank you it is very useful keep making

Glad to help!

[@ismailkh798]

Sir plz slove this q if mean is 5000 and standard deviation is 100 in random variable

[@thomaslong6978]

Why must one convert to z-scores since that step is not necessary with modern technology?

[@XOclone9928]

Where can I find the calculator online

[@phyillismomanyi7742]

Thanks 😊👍

In real life though, you don't get your SAT results along with the standard deviation.... or do you?
