1. Precision of the estimate:

When we calculate the simple sampling error, we find that there is a +/- 4.0 MOE.

In the following estimate, 55% favorable and 45% unfavorable, what is the range the favorable rating could fall given this level of sampling error.

a) 51 to 59%

b) 51 to 55%

c) 55% to 59%

2. Precision of the estimate:

When we calculate the simple sampling error, we find that there is a +/- 2.0 MOE.

In the following estimate, 52% favorable and 48% unfavorable, what is the range the favorable rating could fall given this level of sampling error.

50 to 54%

50 to 52%

52 to 54%

3. Precision of the estimate:

6. In probability sampling, as the size of the sample as a proportion of the population decreases, so does the probability of selection. The larger the sample size, the more precise the estimates are.

True or False?

True

False

7. In probability sampling, as the size of the sample as a proportion of the population decreases, so does the probability of selection.

The larger the sample size, the more precise the estimates are.

If a sample has a sample size of 1000 cases, the margin of error or sampling error would be +/-3.1 points.
