Explanation / Answer

1. A distribution is the variable values and how offen they occurs.

2. When we want to get just basic statistics for your data PROC univariate is one of the procedures we

used PROC univariate was the other.

3. The Cental Limit Theorem states that regardless of the shape of the population, the sampling distribution of the

sample mean becomes approximately normal for n, the sample size, sufficiently large.

4. The P-value is the probability of a type I error.

5. A confidence interval is a range of values used to estimate a population parameter.

6. If you want to print your variables making sure you inputted your data correctly, you would use PROC PRINT.

7. The hypothesis testing is the probability, calculated assuming that the null hypothesis is true, of obtaining a value of the test statistic at least as contradictory to H0 as the value calculated from the available sample data.

8. The P-value is the probability of a type I error based on your sample, or the probability of another sampling producing a mean as far or further in the tail end.

9. A sample is a descriptive measure of a sample.

10. When you want to give names to the categories instead of the numerical names 1,2,3,etc., we would use categorical variable.

11. The statistic is a function of the sample data used as basis for deciding whether H0 should be rejected.
