How to Create Summary Statistics in Google Sheets

In this video, I show you how to generate Summary Statistics like mean, standard deviation, etc in Google Sheets.
Functions and Sample Usage:
Mean: =AVERAGE(A1:A10)
Median: =MEDIAN(A1:A10)
Standard Deviation (Sample): =STDEV(A1:A10)
Standard Deviation (Population): =STDEVP(A1:A10)
Variance (Sample): =VAR(A1:A10)
Variance (Population): =VARP(A1:A10)
Maximum: =MAX(A1:A10)
Minimum: =MIN(A1:A10)
Count: =COUNT(A1:A10)
Sum: =SUM(A1:A10)
First Quartile (Q1): =QUARTILE(A1:A10, 1)
Third Quartile (Q3): =QUARTILE(A1:A10, 3)
Interquartile Range (IQR): =QUARTILE(A1:A10, 3) - QUARTILE(A1:A10, 1)
Mode: =MODE(A1:A10)
Range: =MAX(A1:A10) - MIN(A1:A10)
