Using 0.5 as you alpha level for the levines test, the "sig" value for Levenes test is ______.

Under the section titled t test for equality of mean what are the values for t, df, and Sig 2 tailed? Is the Difference between groups significant? ie <0.05?________________________________________________________

Briefly describe the out come of the experiment. was the difference between music and meditation groups significant? What does that mean in terms of the effect of meditation on reaction time? __________________________________________________________

Step 1

All the answers are based on the output of test performed by you. This will help you read the output and glean insights from it.

From the Group Statistics table below, we can see that there are 13 subjects in each of the groups namely Music group and Meditation group.

Average reaction time of Music group is 0.284472 and Average reactiontime of Meditation group is 0.280959. If we only look at the means, the difference does not seem significant but further analysis of other parameters tells another story.

Step 2

This table has a lot of data but we will not need all of it for our analysis. There are 2 rows - Equal Variances assumed and unequal variances assumed. We will use just one row depending on the value given in **Sig** column (2nd column). If the value here is greater than 0.05, we wil read from the top row ( Equal Variances assumed) assuming that there is no significant difference between the variability of the Music and Meditation groups. If the value under Sig column is less than 0.05. we will conclude that there is statistically significant variability etween the two groups and in this case, we read from the bottom row.

Value under Sig column is 0.12 which is greater than 0.05. We will thus read from top row for our analysis.

Step 3

In top row, we look at the Sig(2-tailed) column value which tells us if there isstatistically significant difference between the means of two groups. If the value is greater than 0.05, we conclude that there is no statistically significant difference between the means of the two groups. If the valu...
