r/AskStatistics on Reddit: Excel function for finding the z score

December 8, 2022 -

Hello,

Can anyone please help me to find the excel function for finding the z value for the area under the curve between the mean and z standard deviations above the mean. See this for reference: https://qph.cf2.quoracdn.net/main-qimg-acde2a1e5b94097e5eefc6466047ec13-pjlq

For example, if the input for the function is 0.4962 (i.e., 99.24% confidence level), the output should be 2.67

Interestingly I could not find any answer on the internet. Maybe I am using the wrong keywords!

Note: NORM.S.INV(probability) is not the function I am looking for (unless I am missing something).
