Standard deviation probability graph
WebbThe Standard Deviation is a measure of how spread out numbers are (read that page for details on how to calculate it). When we calculate the standard deviation we find that generally: Example: 95% of students at school are between 1.1m and 1.7m tall. Assuming this data is normally distributed can you calculate the mean and standard deviation? Webb9 aug. 2024 · 1. Press the STAT button on your calculator. It's in the third column of keys. 2.
