Probability And Significance

Question 1

What is a null hypothesis

Answer 1

Say there isn’t a relationship between the indepednat variable and dependant variable

Question 2

What is an alternate hypothesis ?

Answer 2

Suggest there’s a relationship between the indepednat variable and dependent

Question 3

What is variability ?

Answer 3

Researcher must decide if data collected is strong enough before rejecting the null hypothesis and accepting the alternate hypothesis

Question 4

What is a type 1 error?

Answer 4

When researchers accept the alternate hypothesis in error the data collected has passed the level of significance but really the findings were due to chance variation

Question 5

What is a type 2 error?

Answer 5

When researchers reject the alternate hypothesis in error the data collected hasn’t passed the level of significance but really the ppts not acting as expected is due to chance variation hiding the causal relationship
