______________________________________________________________________________ 3. Use a colon between independent clauses if the second clause summarizes or explains the first. 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.
The Mean Center tool will compute the average for all values in that field and include the result in the output feature class. For line and polygon features, feature centroids are used in distance computations. For multipoints, polylines, or polygons with multiple parts, the centroid is computed using the weighted mean center of all feature parts.
