Research Methods - Spearmans Rho And Pearsons

Question 1

What are the tests for spearman’s and Pearson called

Answer 1

Tests off correlation

Question 2

When do we use spearmans’s Rho

Answer 2

When there is a correlation between two co variables

Data is ordinal

Question 3

When do we use Pearson’s r test

Answer 3

Used when looking for a correlation between two co variables
Data is interval

Question 4

What two things do we need in a spearman’s rho test

Answer 4

Calculated value of rho
Critical value of rho
N

Question 5

How do we find the critical value from critical table when using spearman’s rho

Answer 5

Identify the significance level
Identify if it is one tailed or two tailed test
Number of participants needed

Question 6

How do we find the critical value from critical table when using Pearson’s r

Answer 6

Identify significance level
Identify if one tailed or two tailed
Calculate DF value which is number of participants - 2

Question 7

When are the realstes from both spearman’s rho and Pearson’s r significant

Answer 7

When calculated value of rho or r is more than the critical value of rho or r , the results are significant

Question 8

How do we write out the results for spearman’s rho

Answer 8

As the calculated value of rho () is equal to or more than the critical value of rho when (N = —- p<0.05) the results are significant. We reject the null hypothesis. There is a significant positive or negative correlation between —— and ———
