middle value in the data and means that fifty percent of the beers have calories above 148 and fifty percent of the beers have calories below 148. The mode, 148, is the value, or number of calories that occur most frequently in the data set. The standard deviation is the typical spread around the mean number of calories per beer and is +/- 29.90221 calories. The range of calories per beer is 143 and measures the total spread of the data from the minimum value of 58 calories per beer to the maximum
