25. Quiz: Shape and Outliers (Final Quiz)
Histograms
Let the histogram on the left be Histogram 1 and the histogram on the right be Histogram 2.
Quick Notes
Pay attention to the scale of these two graphs. The first is dealing with much higher numbers.
The median is the middle number and is not affected by outliers.
The average factors in all the numbers so outliers will bring the average towards them.
Left Skewed is when the graphs start with a low frequency and then slopes up. Right Skewed is when the graph starts with a high frequency and slopes down.
