To compare the dispersion of differently scaled data sets (many be different units like age in years and weight in pounds), one should use relative measures of dispersion. One such unit-less (dimension-less) measure is coefficient of variation (CV), which is given by SD/Mean.
Jan 12, 2020 · This wikiHow teaches how to compare different sets of data in Excel, from two columns in the same spreadsheet to two different Excel files. 1. Highlight the first cell of a blank column. When comparing two columns in a worksheet, you'll be outputting your results onto a blank column.
Jan 31, 2017 · Pearson correlation is weaker in this case, but it is still showing a very strong association due to the partial linearity of the relationship. The data in Example 2 shows clear groups in X and a strong, although non-monotonic, association for both groups with Y. In this case, Pearson correlation is almost 0 since the data is very non-linear.
Data from the 1998 through 2000 seasons of the National Football League, giving year and week of the game, home and visiting teams, score, and pointspread. The same data for the 2001 through 2008 seasons, minus the pointspread data. NLYS. Filename: NLYS.XLS A small subset of data from the National Longitudinal Youth Survey.

Jul 31, 2018 · I've two sets of data, which I would like to correlate. The number of elements in both the data sets are different and have different respective dates.
4.Covariance is a measure of a correlation, while correlation is a scaled version of covariance. 5.Covariance can involve the relationship between two variables or data sets, while correlation can involve the relationship between multiple variables as well. 6.Correlation values range from positive 1 to negative 1.
