What I said previously is that even if the variances are equal the t test with unequal variances should be pretty accurate. Since the p-value > .55 for the t test for MBEA, then you cannot reject the hypothesis that the (population) means for MBEA are equal. Since the p-values for the other tests are less , you conclude with 95% confidence that the means for these dimensions are equal.

The terminology of type I /II errors seems a bit counter-intuitive. If a test result is wrong, then I would agree to call that a 8766 false 8767 test result (. wrong/error= false and accordingly, type I and type II are both called 8766 false 8767 ). However, if the null hypothesis H5 is 8766 rejected 8767 by the test, then I would call that a 8766 negative 8767 test result (. rejected = negative). Hence the type I error event that a true Ho is rejected, would be called a 8766 false negative 8767

Vicky,
The non-central distributions are used to calculate beta or power. The details are shown in various places on the website. .

Hi. I 8767 m doins a research on motivation and de-motivation among students. I 8767 m using 8 independent variables. I 8767 m testing how the 8 IV affect motivation and de-motivation. Should I use null hypotheses to test motivation and de-motivation? At the same time I 8767 m using 7 dependent variables(motivation and de-motivation).
Would appreciate your help. tq
My second book, The Righteous Mind, uses the rider and elephant to understand morality, politics, and religion. It picks up where The Happiness Hypothesis left off in the concluding chapter -- about the need to look for wisdom in the minds of those with whom you disagree.
You can not PROVE the hypothesis with a single experiment, because there is a chance that you made an error somewhere along the way.
A study was designed to compare three different methods for reducing stress. Sixty employees in a corporation were randomly assigned to each of the following groups for a two-week period: exercise, relaxation training, and management skills training (learning to set priorities, communicate effectively, resolve conflicts). Data consisted of subject scores on a measure of stress in the workplace taken after each two-week training period.
8775 Acceptance Interval 8776 , indeed?
There are lots of people that uses this designation
I do prefer to name it 8775 No-rejection 8776
What do you think about?
Hi Simon,
Here, the word positive is used since the null hypothesis is actually True. The word false is used since the conclusion is wrong, namely to reject the null hypothesis.
