Gender b. First, what is the level of measurement for each variable? For each variable, identify which measures of central tendencies may be most appropriate. c. For the interval- and ratio-level variables of this list, use the mean and median to describe the variables' distri- bution. ...
The mode is the value that appears most frequently in a data set. A set of data may have one mode, more than one mode, or no mode at all. Other popular measures of central tendency include the mean, or the average of a set, and the median, the middle value in a set. ...
The rest of the total return (what the S&P 500 itself earned) arguably has nothing to do with the manager’s unique ability. Portable alpha strategies use derivatives and other tools to refine how they obtain and pay for the alpha and beta components of theirexposure. ...
