Inferential Statistics Test of Correlation

Question 1

The probability of getting a sample statistic or a mean extreme sample statistic in the direction of the H1 when the H0 is true.

Answer 1

P-value (Probability value)

Question 2

It is the actual area under the standard normal distribution curve representing the probability of a particular sample statistic or a more extreme sample statistic occurring if the H0 is true.

Answer 2

P-value (Probability value)

Question 3

7 Steps for P-value method are:

Answer 3

1. State the null hypothesis (H0) and the alternative hypothesis
   (H1).
2. Choose the level of significance, α, and the sample size
3. Determine the test statistic and sampling distribution.
4. Compute the test value.
5. Determine the p-value.
6. Make a statistical decision.
7. State the conclusion

Question 4

Use to determine if there is linear relationship between the two variables.

Answer 4

Pearson’s Product Moment Correlation Test

Question 5

It is a parametric statistical test used to measure the degree of relationship (correlation coefficient) between two sets of data.
