Seeing how closely the measuring instrument relates to theoretical constructs
Taking another measuring instrument and measuring the same participants and comparing the 2 sets of scores/results and if they agree the measure has high validity
Ask an expert(s) in the field to assess the measuring instrument to see if they are an accurate measure of the subject
Taking another measuring instrument and measuring the same participants and comparing the 2 sets of scores/results and if they agree the measure has high validity
7. What is repeatability?
Findings of a study can be replicated by other researchers at a different time
When all sources of bias are reduced and/or eliminated
8. When should a Chi-squared be used?
It finds nominal data, its a test of difference and the categories are independent from one another
It's an independent groups design, at least ordinal data is collected and a test of difference
It's a matched-pairs or repeated measures design, at least ordinal data has been collected and its a test of difference
Its finding a correlation/relationship between 2 variables and its collecting at least ordinal data
9. What is empirical evidence?
Data being collected through direct observation or experiment and it doesn't rely on argument or belief
Idea that only source of knowledge comes from experience
10. What is type 1 error?
Where the researcher accepts the null hypothesis (or rejects the research/alternative hypothesis) when in fact the effect is due to chance as the level of significance isn't stringent enough
Where the researcher rejects the null hypothesis (or accepts the research/alternative hypothesis) when in fact the effect is due to chance as the level of significance isn't stringent enough
Where the researcher accepts the null hypothesis (or rejects the research/alternative hypothesis) when in fact the effect isn't due to chance as the level of significance is too stringent
Where the researcher rejects the null hypothesis (or accepts the research/alternative hypothesis) when in fact the effect isn't due to chance as the level of significance is too stringent
11. When should Wilcoxon test be used?
It finds nominal data, its a test of difference and the categories are independent from one another
It's a matched-pairs or repeated measures design, at least ordinal data has been collected and its a test of difference
It's an independent groups design, at least ordinal data is collected and a test of difference
Its finding a correlation/relationship between 2 variables and its collecting at least ordinal data
12. A directional hypothesis is also known as a..........
One-tailed hypothesis
Operationalised hypothesis
Null hypothesis
Two-tailed hypothesis
13. What is objectivity?
When all sources of bias are reduced and/or eliminated
Findings of a study can be replicated by other researchers at a different time
14. What is a type 2 error?
Where the researcher rejects the null hypothesis (or accepts the research/alternative hypothesis) when in fact the effect isn't due to chance as the level of significance is too stringent
Where the researcher rejects the null hypothesis (or accepts the research/alternative hypothesis) when in fact the effect is due to chance as the level of significance isn't stringent enough
Where the researcher accepts the null hypothesis (or rejects the research/alternative hypothesis) when in fact the effect isn't due to chance as the level of significance is too stringent
Where the researcher accepts the null hypothesis (or rejects the research/alternative hypothesis) when in fact the effect is due to chance as the level of significance isn't stringent enough
15. Why would a directional hypothesis be used instead of a non-directional?
Findings of previous research pointed in a particular direction
Its easier to write a directional
There's no previous research on this subject
16. What is construct validity
Taking another measuring instrument and measuring the same participants and comparing the 2 sets of scores/results and if they agree the measure has high validity
Seeing how closely the measuring instrument relates to theoretical constructs
Ask an expert(s) in the field to assess the measuring instrument to see if they are an accurate measure of the subject
17. When should a Mann-Whitney test be used?
It finds nominal data, its a test of difference and the categories are independent from one another
Its finding a correlation/relationship between 2 variables and its collecting at least ordinal data
It's an independent groups design, at least ordinal data is collected and a test of difference
It's a matched-pairs or repeated measures design, at least ordinal data has been collected and its a test of difference
