PSY 210 Module 1 Assignment 3 Research Design Questions NEW

 

Suppose you were going to create your own study to examine what course-delivery format (online, blended, or face-to-face) leads to the best performance in a psychological statistics class. In a paper identify the following for your study:

 

What is your research question?

What is your hypothesis (both null and alternate)?

Is this a qualitative or quantitative design (based on type of variable collected) and why?

Is this a descriptive, correlational or experimental design and why?

What would be an example of a variable for this study that could be measured on a nominal scale? Ordinal scale? Interval scale? Ratio scale?

Once you have collected your data, would you use inferential or descriptive statistics and why?

Create a sample frequency distribution for one of the variables. Choose either a simple or grouped frequency distribution and explain your choice.

PSY 210 Module 4 Assignment 2 Analyzing with Anova NEW

 

Submit your answers to the following questions using the ANOVA source table below. The table depicts a two-way ANOVA in which gender has two groups (male and female), marital status has three groups (married, single never married, divorced), and the means refer to happiness scores (n = 100):

 

1.What is/are the independent variable(s)? What is/are the dependent variable(s)?

2.What would be an appropriate null hypothesis? Alternate hypothesis?

3.What are the degrees of freedom for 1) gender, 2) marital status, 3) interaction between gender and marital status, and 4) error or within variance?

4.Calculate the mean square for 1) gender, 2) marital status, 3) interaction between gender and marital status, and 4) error or within variance.

5.Calculate the F ratio for 1) gender, 2) marital status, and 3) interaction between gender and marital status.

6.Identify the critical Fs at alpha = .05 for 1) gender, 2) marital status, and 3) interaction between gender and marital status.

7.If alpha is set at .05, what conclusions can you make?

Source Sum of Squares (degrees of freedom [df]) Mean Square Fobt. Fcrit.

Gender 68.15 ? ? ? ?

Marital Status 127.37 ? ? ? ?

Gender * Marital Status (A x B) 41.90 ? ? ? ?

Error (Within) 864.82 ? ? NA NA

Total 1102.24 99 NA NA NA

 

Please Note: The table that you see in the assignment has been slightly modified from the one presented in the module notes since it is beyond the scope of this unit to have students calculate p values. Instead you are asked to calculate the F value and compare it to the critical F value to determine whether the test is significant or not.

PSY 210 Module 2 Assignment 2 Conducting a Z-Test NEW

 

A researcher predicts that watching a film on institutionalization will change students attitudes about chronically mentally ill patients. The researcher randomly selects a class of 36 students, shows them the fulm, and gives them a questionnaire about their attitudes. The main score on the questionnaire for these 36 students is 70. The score for a similar class of students who did not see the film is 75. The standard deviation is 12. Using the five steps of hypothesis testing and the 5% significance level ( i.e. alpha= .05). does showing the film change students attitudes towards the chronically mentally ill?

 

1. What does it mean to set apha at .05?

 

2. What is your null hypothesis? Alternate hypothesis?

 

3. Is this a one- tailed or two-tailed hypothesis?

 

4. What is the critical z?

 

5. Suppose the obtained z was -2.5. Do you reject or fail to reject the null hypothesis?

 

6. State in words what you have found.
