If We Were to Graph the Relationship of Sample Size

question 59

Multiple Choice

If we were to graph the relationship of sample size (x-axis) to sample accuracy (y-axis) , we would notice that:

• A) There is a linear relationship between size and accuracy.
• B) Accuracy increases quickly, up to about sample size 500, and then accuracy levels off with relatively small gains made even when sample size is increased to as much as 2,000.
• C) Accuracy increases quickly, up to about sample size 5,000, and then accuracy levels off with relatively small gains made even when sample size is increased to as much as 200,000.
• D) Accuracy increases quickly, up to about sample size 50, and then accuracy levels off with relatively small gains made even when sample size is increased to as much as 100.
• E) We cannot graph just sample size and accuracy because we must also include the level of confidence and the variability within the sample data.
