- What is the median of a data set?
- The middle value when the data is arranged in numerical order
- What is the mode of a data set?
- The value that appears most frequently
- What is the range of a data set?
- The difference between the highest and lowest values
- What does standard deviation measure?
- How spread out the values in a data set are from the mean

- What does a scatter plot show?
- The relationship between two numerical variables using individual plotted points
- What does a positive correlation between two variables mean?
- As one variable increases, the other tends to increase as well
