+## Notes
+
+**Definition:** A boxplot is a plot that shows the distribution of quartiles.
+
+These plots show the IQR (interquartile range - Q2 and Q3) filled in and then lines out to the Q1 and Q4 points. These also have dots for some outliers. This is also known as a box and whisker plot.

+
+## Notes
+
+**Definition:** Crosstabulation in stats is a way to display three dimensional information. Across the top and side you have some classes and then in the table itself we have the information of the cross-sectional group.
+
+ex:
+
+Admittance Male Female
+
+ Admitted 1198 557
+ Rejected 1493 1278
+
+
+This data can be shown using a [[MosaicPlot.md]] for graphical viewing with sized boxes.
