## Can you use a TI-84 for statistics?

TI-84: CALCULATING SUMMARY STATISTICS Use the STAT, CALC, 1-Var Stats command to find summary statistics such as mean, standard deviation, and quartiles.

## What mode should my calculator be in for statistics?

Almost all calculators come with both DEG & RAD mode. You should use the mode which matches with the given data in the question. For example: if we need to find cos(v) and v=60°, then use degree mode because given angle is in degree. If the given angle is in radians then use RAD mode.
