. Create standardized scores for all scale variables (price through alcohol). Which beverages have positive standardized scores on every variable? What does this mean?
To create standardized scores for the variables (price through alcohol), you can follow these steps:
1. Calculate the mean (average) of each variable.
2. Calculate the standard deviation of each variable.
3. Subtract the mean from each individual observation of the variable.
4. Divide the result by the standard deviation.
Once you have the standardized scores for each variable, you can determine which beverages have positive standardized scores on every variable. Simply look for the beverages that have a positive value for each of the standardized scores.
If a beverage has positive standardized scores on every variable, it means that it tends to have higher values on each of the variables compared to the average. It suggests that these beverages are relatively more expensive, have higher calories, and higher alcohol content compared to other beverages in the dataset.
