but for data analysts, an important task would be to generate a frequency with 2, 3 or even more variables. Such a table is also called a Cross Table or a Contingency Table. When talking about a two way frequenc
Specific “Means” commonly used in Stats You’ll probably come across these in an elementary stats class. They have very narrow meanings: Mean of the sampling distribution: the center of aprobability distribution, especially with respect to theCentral Limit Theorem. It’s an average (of sorts)...

For a set of raw data, to make a frequency distribution. The lower bound of the first class is an even multiply of the width of the class interval. The number of classes includes the minimum and maximum values. There should be no missing or excess class intervals....
For reac04, we see some low outliers as well as a high outlier. We can find which values these are in the bottom and top of its frequency distribution as shown below.If we see any outliers in a histogram, we may look up the exact values in the corresponding frequency table.We can ...
