Week 10 Celebration of Knowledge (20 pts)

Objective: the objective for this week’s Celebration of Knowledge is for you to apply your newly acquired statistical knowledge to answer the questions below.

Directions: to complete this assignment, read through each of the questions and provide your answer.

Due: March 17th (11:59 PM)

1. [1 pt] You examine results and notice there is a significant, positive linear relationship between TIME SPENT STUDYING FOR EXAM 2 and EXAM 2 SCORES (r = .76, p = .05). Explain what this means (i.e., explain what can we conclude about the direction and strength of relationship between the two variables):

2. [1 pt] What is the shared variance between the two variables in the previous question? In your answer provide: the r2 value, the effect size, and describe what this means.

(a) r2 value and effect size:

(b) What does this mean?:

3. [2 pt] Jake was conducting a study examining the association between the amount of time spent online and knowledge of world affairs. He found a significant, positive association between the two variables, r = .38, p < .05. When Jake presents his results to you, he tells you that the findings from the study demonstrate that spending a lot of time online causes an increase in one’s knowledge about world affairs. You are concerned that Jake doesn’t understand correlation and causality, so you decide to write a brief note explaining how Jake should interpret his results. Provide your brief response below.

Use the output below to answer the following questions.

*Correlation Output*
	Number of social media accounts	Quality of online communication (1-10 scale)
Number of social media accounts	Pearson Correlation	1.000	-.857**
	Sig. (2-tailed)	.	.000
	N	24	24
Quality of online communication (1-10 scale)	Pearson Correlation	-.857**	1.000
	Sig. (2-tailed)	.000	.
	N	24	24

4. [1 pt] Provide the r and p values. For the p-value simply indicate if p is above or below .05. r = , p

5. [2 pt] Describe what the r value tells us about the relationship between the number of social media accounts one has and the quality of one’s online communication.

Use this output to answer the following questions.

Predictors: Humanity as ingroup Outcome: Perspective taking

Reminder: Remember how to interpret the p-value! When interpreting the p-value report if p is below (p < .05) or above (p < .05) .05.

6. [1 pt] The model accounts for ________ of the variance (p _____) in perspective taking.

7. [2 pts] Is humanity as ingroup a significant predictor of perspective taking? Provide the regression weight, interpret the p-value, and interpret the regression weight below. b =________ , p _________

Interpret the regression weight:

8. [3 pts] If a participant’s humanity as ingroup score is 3, what will their perspective taking score be? Use the regression formula ( y = bx + a) and show your calculations below.

Use this output to answer the following questions.

Predictors: Humanity as ingroup, Empathy, Depression, Intercultural communication anxiety

Outcome: Perspective taking

Reminder: Remember how to interpret the p-value! When interpreting the p-value report if p is below (p < .05) or above (p < .05) .05.

9. [1 pt] The model accounts for ________ of the variance (p _____) in perspective taking.

10. [2 pts] Is depression a significant predictor of perspective taking? Provide the regression weight, interpret the p-value, and interpret the regression weight below. b =________ , p _________

Interpret the regression weight:

11. [2 pts] Is intercultural communication anxiety a significant predictor of perspective taking? Provide the regression weight, interpret the p-value, and interpret the regression weight below. b =________ , p _________

Interpret the regression weight:

12. [2 pts] Is empathy a significant predictor of perspective taking? Provide the regression weight, interpret the p-value, and interpret the regression weight below. b =________ , p _________

Interpret the regression weight:
