A colon is used to introduce an idea that is an explanation or continuation of the one that comes before the colon. The colon can be considered as a gateway inviting the reader to go on. Look at these examples: Ben suddenly canceled his evening plans for a simple reason: his car was out of gas.
Measures of Center: Mean, Median, and Mode Measures of center generally tell us about the middle, or center, of a distribution. They are the mean, the median, and the mode. Each plays a useful role in Statistics. The Mean The mean, or arithmetic average, is calculated by adding all the data values and dividing by the number of values.
Usage. 1  The mean center is a point constructed from the average x and y values for the input feature centroids. 2  Use projected data with this tool to accurately measure distances. 3  The x and y values for the mean center point features are attributes in the Output Feature Class. The values are stored in the fields XCOORD and YCOORD. The Case Field is used to group features for separate mean center computations.
