Question: Suppose you have data with multiple variables (columns) and you have calculated each variable's mean and standard deviation. How would you then describe these variables

Suppose you have data with multiple variables (columns) and you have calculated each variable's mean and standard deviation. How would you then describe these variables by comparing the means and standard deviations and why is it so important when making comparisons of different variables? Example: You have to choose between two stock portfolios, A and B. Portfolio A has a mean of 100 and a standard deviation of 10, whereas portfolio B has a mean of 140 and a standard deviation of 40. Which portfolio would you choose, and why based on this Discussion
