4. Drawing Statistical Graphs, and Performing
Statistical and Regression Calculations
When you want to check the correlation between two sets of data (such as temperature and
the price of some product), trends become easier to spot if you draw a graph that uses one set
x
of data as the -axis and the other set of data as the
With the spreadsheet you can input the values for each set of data and draw a scatter plot or
other types of graphs. Performing regression calculations on the data will produce a regression
formula and correlation coefficient, and you can overlay a regression graph over the scatter
plot.
S SHT mode graphing, statistical calculations, and regression calculations use the same

functions as the STAT mode. The following shows an operation example that is unique to the
S SHT mode.
