For this standard, students will need to practice with a large range of situations in order to generalize which ones yield variability and which situations do not. Once students begin to see that the more specific the question, the less variability, they can begin to predict when a situation will vary and when it will not.
Which of the following situations would yield the most variability in the data collected? Justify your thinking.
a) The daily temperatures of a city for the last 2 weeks
b) The number of goals scored in a recent soccer tournament
c) The number of students who attended the theatre performance last Friday
d) The amount of calories eaten in a day
