Inferential Tests

Question 1

What’s inferential tests

Answer 1

Helps makes references about our data and draw meaningful conclusions from number(Quantitative data)

Question 2

What’s statistical tests

Answer 2

Aim to find out whether it’s likely that any pattern in the data could have arisen by chance or variables

Question 3

What’s significance level

Answer 3

Arisen due chance

Usually set at p<0.05(5%)

Question 4

Paramedic tests-design and data

Answer 4

1)Correlation-ORDINAL/INTERVAL- Spearmans Rho
2)Independent Measures;
NOMINAL-Chi square
ORDINAL- Mann Whitney
3)Repeated Measures/Matched pairs;
NOMINAL-Binomial sign
ORDINAL- Wilcoxon

Question 5

Chi square test

Answer 5

• test of association which looks for patterns in nominal data
• tests whether distribution of results differs from what would be expected on the basis of chance alone
• compare actual data with data set based on null hypothesis
• observe value>critical value=Null rejected

Question 6

Mann Whitney U test

Answer 6

• used to find whether there’s a significant difference between 2 sets of data
• observe value

Question 7

Binomial sign test

Answer 7

• Used to find out whether there’s a significant difference between 2 sets of data-Must come from the same parts
• observe

Question 8

Wilcoxon tear

Answer 8

• It’s use is that same as Binomial

- observe=critical =Null rejected

Question 9

Spearmans rho test

Answer 9

• Used to find whether there’s a relationship between 2 variables
• observe>critical =Null rejected
