To find the average GPA of all students in a university, use all honor students at the university as the sample. The data are because.continuous the data can take on any value in an interval B. Therefore this is discrete data. The ordinal data only shows the sequences and cannot use for statistical analysis. This is important to know when we think about what the data are telling us. By using simple random sampling, select states to be part of the cluster. Your instructor will give each group one six-sided die. In some situations, having small samples is unavoidable and can still be used to draw conclusions. The data .
