Sameer Borate:
Calculating descriptive statistics in MySQL
April 08, 2014 @ 10:46:22

Sameer Borate has shared some examples of how to generate some meaningful statistics about the contents of your database in a new post to his site today.

Descriptive statistics can be quite useful for simple analysis of records in a database. For example, to calculate average numbers of sales or products for a particular duration, or the Variance of sales for a month etc. We can easily calculate standard descriptive statistic measures in MySQL such as MEAN, SUM, STANDARD DEVIATION, VARIANCE, MIN and MAX using built-in functions.

He includes both the SQL and a bit of PHP code showing how to get these statistics (based on a simple data set of student scores). The PHP is required to more correctly evaluate the median and mode values as it's easier to evaluate those in PHP.
