HELP !!!
Which statistics concept is described?
Choose from these answers:
[(A):statistical test] [(B):Null Hypothesis] [(C):alpha] [(D):one-tailed test] [(E):two-tailed test] [(F):Type I error] [(G):Type II error] [(H):the statistic Z]
1)When a hypothesis is that two groups will not be equal, but does not predict which group's scores will be larger or smaller.
2)the idea that your results happened by random chance or error, not due to any real differences.
what should be the answer? Help will be greatly appreciated.
To answer this question, we need to understand the descriptions of each statistics concept and match them to the given options.
1) The description "When a hypothesis is that two groups will not be equal, but does not predict which group's scores will be larger or smaller" refers to a two-tailed test, as it considers both possibilities of the groups being different in either direction.
2) The description "the idea that your results happened by random chance or error, not due to any real differences" refers to the concept of Type I error, which is when we incorrectly reject the null hypothesis and conclude that there is a significant difference when in fact there is not.
Based on these descriptions, the answers are:
1) (E) two-tailed test
2) (F) Type I error
I hope this explanation helps you understand how to arrive at the answers!
