D2.2 Make and test predictions about the likelihood that the categories in a data set from one population will have the same frequencies in data collected from a different population of the same size.
Skill: To Formulate and Verify Predictions
Data can differ from population to population and can be used to make predictions that are not based solely on feelings or opinions. Probability is about predicting future events (as opposed to statistics which is about analyzing past events).
Knowledge: Population of the Same Size
In order to make a fair comparison in grade 1, it is important for students to collect data from a population of the same size (for example, same number of objects in a bin, days in a month, grade 1 students).
