(c) on a test, each student is given a grade of a, b, c, d, or f. which measure tells the grade given most often?
mean median mode
Step1: Analyze house - price data
The house - price data has an outlier ($473$), and the mean is affected by outliers. The median is a better measure for skewed data with outliers.
Step2: Analyze soft - drink data
The soft - drink data is a set of numerical values without obvious outliers. The mean can be used to summarize the central tendency as the data is relatively symmetric.
Step3: Analyze grade data
The grade data is categorical. The mode is the measure that tells the most frequently occurring category.
