Updated: Mar 16, 2023

Take a look below to learn everything you need to know about the STAT button on your calculator: how to find trend-lines of all kinds; how to find the mean, median, standard deviation, and interquartile range of a data set; how to use frequency tables; how to graph scatter plots, histograms, box-and-whisker plots; and more. Plus troubleshooting tips for some of the most common problems, like lists disappearing or the R² value not displaying for regression models.

Where is the STAT button on a TI-84 calculator?

Find a linear regression or trend-line

Find a quadratic, cubic, quartic, logarithmic , exponential, or logistic regression

Graph a scatter plot

Turn on R² value (correlation coefficient) for linear regression

Find 5 number summary (max, min, median, first quartile, third quartile), mean (average), and standard deviation of a list

Input a frequency table

Draw a box and whisker plot

Draw a histogram

Restore missing lists (L1, L2...) under STAT > Edit

So I am trying to make 2 different lines, one with L1 and L2, and one with L1 and L3. My calculator doesn't have the option to change L2 to L3 when trying to find the slope intercept form. What do I do?

(Side note, this article looks like instructions for a TI-84 Plus CE, which is just color edition, and I have the TI-84 Plus, which could make a difference, but IDK)
