What are the assumptions that must be met about her data before she can correctly use an independent t-test to test the hypotheses? Why? How would she see if her data met these assumptions? How much room does she have to violate any of these assumptions and still get accurate results from the t-test?
September 4, 2018Read the poem carefully and then in a well-written essay explain the speaker’s attitude toward love and how he reveals that attitude. You may wish to discuss figurative language, metrical pattern, tone, and other poetic devices that seem appropriate.
September 4, 2018Describe a way to measure the DV so that each participant would have one score at the end. Would this DV measure be on a continuous scale of measurement? Why is this important? Explain and justify.
For clarification purposes, please provide separate answers and references for each module. Thanks
MODULE 2
A
How is sample size related to statistical tests and outcomes? Give a specific example. Why is it important to plan the sample size before collecting data?
B
Fill in the following for a possible study with one independent variable (IV) with two conditions/treatments and a dependent variable (DV) that is measured on a continuous scale (interval or ratio):
· Independent variable = ______________
· Condition A = ______________
· Condition B = ______________
· Dependent variable = _______________
· How do you know this DV is measured on a continuous scale?
· How would you word the null hypothesis for your sample study?
· How would you word the alternative hypothesis for your sample study?
· What alpha level would you set to test your hypothesis? Why?
MODULE 3
A
What is the primary purpose of inferential statistics? How might inferential statistics be applied to your intended research study? Explain.
B
Researchers often assume a normal distribution of data. Why is this significant in quantitative research? Explain.
MODULE 4
A
Mary is planning a study to see if learning of 6th graders on a math lesson is affected by background noise level. She wants to use a t-test for independent groups to analyze her results. Help her plan her study. What is her independent variable (IV) here? Describe two conditions she could create for the IV in her study. What is her dependent variable (DV) here? Describe a way to measure the DV so that each participant would have one score at the end. Would this DV measure be on a continuous scale of measurement? Why is this important? Explain and justify.
