Question

See attachedQuestion 1  Researchers wanted to figure out what type of treatment was more effective in treating  depression. A sample of 15 participants were randomly assigned to one of three groups:  psychotherapy, antidepressant medication, or no treatment. The treatment lasted 6 months. After  the 6-month treatment program, participants were asked to complete the Beck Depression  Inventory (Beck, Steer, Ball, & Ranieri, 1996) to determine if therapy type led to differences in  level of depression as measured by lower scores on Beck Depression Inventory. The scores  potentially range from 0-63. The researchers hypothesized a difference in levels of depression  across the three treatment groups. Write a paragraph describing and interpreting the results.   Participant #: 1 Age: 30 Gender: Mo. \e.

Forty participants were randomly assigned to one of four groups.  The four groups were a combination of blue or red walls and classical or heavy metal music. The  participants were randomly assigned to a room and music type for duration of 15 minutes. After  the 15 minutes, participants were asked to rate their level of relaxation using a 7-point scale (1 =  not at all relaxed to 7 = extremely relaxed). The following predictions were made. Participants in  the condition with blue walls will be more relaxed than participants in the condition with red  walls (main effect 1). Participants in the condition with classical music will be more relaxed than  participants in the condition with heavy metal music (main effect 2). When participants are in the  heavy metal music condition they will be more relaxed when in the blue room compared to the  red room. In the classical music condition, the pattern will be the same but more pronounced  (interaction). Write a paragraph describing and interpreting the results.

Question No.1
One way anova:
Here no of elements selected = 15 participant
Groups = 3 
Each group contained 5 persons in that
Since here are concerned about the various types of treatments and their effects we ignore the variable sex of the participant for time being.
We treat variables as the treatment programs, namely psychotherapy, antidepressant medication, or no treatment.
The results given individually is first consolidated as follows:
We set up hypotheses as

We are given sum of squares between groups is 2129.2 and degrees of freedom = no of groups -1 =2
Hence we get Mean squares between groups as 1064.6
Within groups we have sum of squares as 146.
