Question

imagine now that 12 of your stat 1350 classmates each survey a random sample of n = 50 college students. each classmate then determines the proportion of the students in the sample who were initially undecided about what major to pursue when they started college. the graph below—called a dot plot—shows each of these sample proportions. each proportion appears as a dot above a number line, and the number line gives us different values of our sample proportions. if any dots are stacked in a column, it would mean that more than one sample resulted in that sample proportion. for example, there are three dots stacked in a column at 0.38, and this means that three sample proportions were 0.38. 14. look carefully at the dot plot above. the sample proportions are not all the same. this means we have __________________ among the sample proportions.

Explanation:

Since the sample proportions are not all the same, this indicates that there is a variation or spread in the values of the sample proportions. In statistics, when values of a statistic (here, the sample proportion) from different samples are not identical, we say there is variability among them.

Answer:

variability
