Assignment: How to evaluate alternative hypotheses

READING

a. In the last assignment, you learned about reliability and validity as applied to research. In this assignment, you’re going to learn about threats to internal validity, which can also be considered candidates for alternative hypotheses.

b. To learn nine candidates for alternative hypotheses:

1. Watch the video “How to Evaluate Alternative Hypotheses.” 2. While watching this video, take notes, as well as stop the video and play it

back, whenever you’re not sure if you’re understanding something. 3. For each of the nine candidates for alternative hypotheses mentioned in

the lecture video, write down in your notes: ▪ the name of the alternative hypothesis; ▪ a definition, in your own words, of that alternative hypothesis; and ▪ at least one of the examples of that alternative hypothesis that was

given in the lecture video.

WRITING ASSIGNMENT

c. Now, for each of the nine candidates for alternative hypotheses:

1. Think of and write down one more example of that alternative hypothesis. 2. Your example must not be one that was mentioned in the lecture video.

d. Go to the discussion board forum “Assignment #10, Part 1: Alternative hypotheses” and make a new post in which you list for each of the nine candidates for alternative hypotheses:

1. the name of the alternative hypothesis; 2. a definition, in your own words, of that alternative hypothesis; 3. at least one of the examples of that alternative hypothesis that was given

in the lecture video; and 4. your own example of that alternative hypothesis.

e. NOTE: 1. You won’t be able to see other students’ posts on the “Assignment #10,

Part 1: Alternative hypotheses” forum until after you submit your own post.

Unit 9: Assignment #2 (due before 11:59 pm Central on THU JUL 19):

WRITING ASSIGNMENT

a. Now it’s time to apply what you’ve learned about how to evaluate alternative hypotheses when you’re reading scientific articles that are reported in the popular press.

b. Find five popular press articles that report the results of a scientific study AND for which at least one of the nine alternative hypotheses you’ve learned, excluding Correlation Isn’t Causation, could explain the results.

c. Go here for a list of some popular press science websites.

d. Go to the discussion board forum “Assignment #10, Part: Applying knowledge about alternative hypotheses” and make a new post in which you list (in a numbered list) the five popular press articles you have found. For each of the five popular press articles:

1. Provide a link to the popular press article (use the name of the popular press article for the text that you embed as a link, e.g., Why you shouldn’t eat late at night, according to science).

2. Identify the alternative hypothesis that could explain the study’s results. 3. Explain, in at least 50 words, how the alternative hypothesis can explain

the study’s results.

4. Remember that you can’t use the alternative hypothesis Correlation Isn’t Causation for this assignment (because you analyzed popular press articles for that alternative hypothesis previously).

WRITING ASSIGNMENT

a. Select your favorite three alternative hypotheses, and teach all three to three separate people.

o You can teach each person via email, phone, text, Facebook, Skype, in person, or any other communication medium.

o But you must teach all three of your favorite alternative hypotheses to three separate people at three separate times.

o AND you cannot teach Correlation Isn’t Causation, because you already taught people that alternative hypothesis (in Unit 4).

b. When you’re teaching your favorite three alternative hypotheses to three different people, be sure to provide examples of each of the three alternative hypotheses.

c. To make sure each of the three people learn your favorite three alternative hypotheses, ask each person to tell you another example (one that you did not tell them) of each of the three alternative hypotheses.

d. Go to the discussion board forum “Assignment #10, Part 3: Teaching alternative hypotheses” and make a new post of at least 200 words. Describe

1. which three alternative hypotheses you taught the three people; 2. why you chose those three alternative hypotheses; 3. how you taught the three persons the three alternative hypotheses (i.e.,

what words did you use to explain each hypothesis and what example or examples did you use?); and

4. for each of the three people you taught,

▪ state each of the three persons’ initials (e.g., MG) ▪ state each person’s approximate age; and ▪ state the examples each person provided of the three alternative

hypotheses.
