Partway through my first semester in college, I tried drawing and labeling pictures as a study tool, and my grades on multiple choice exams improved. I decided to design an experiment to see if this same trick works more generally. I split up students into two groups in my LIFE 102 class:
Group A were given the PowerPoint slides for lecture and asked to review the material for their weekly quiz based on the lecture notes only.
Group B were given the same PowerPoint slides during lecture and asked to draw the content visible on the slides during lecture in their notebooks.
I asked students to share their notes with me so I could confirm which students drew their own pictures and which students used lecture notes only. Then, I evaluated their quiz grades.
Write an alternative hypothesis and a null hypothesis for my experiment. Then write a prediction for each of these hypotheses.
Label them clearly, as in this structure:
Alternative Hypothesis: [general statement of a phenomenon…
Does blood type determine your personality?
In a study aimed at answering this question, a
random sample of 100 adults was given a
personality test, and a comparison was made
between the scores on the
introversion/extroversion scale and blood
type (A, B, AB, О).
(a) Is this an experiment, a retrospective
observational study, or a prospective
observational study?
(b) Comment on the extent to which
inferences can be drawn about a larger
population and whether cause and effect can
be established.
What is the topic in statistics that is the most difficult ? Please be specific here. Saying “I don’t understand anything” or “I don’t understand module 7” are very vague and difficult for people to help with. Instead, try and narrow it down to something like “I am struggling computing Cohen’s d” or “I am struggling to determine whether we reject or fail to reject the null hypothesis.”

Write the type answer.arrow_forwardYou are starting a dairy farm and have read that dairy cows make more milk when they are relaxed. Since your mother listens to classical music to relax, you wonder whether cows listening to classical music would make more milk. You have 40 cows. You decide to test the hypothesis that playing classical music will make cows produce more milk. Briefly summarize how you will design a controlled experiment to test your hypothesis. Then Identify the explanatory variable, the response variable, and the controlled variable in your study. And, finally, make a prediction and explain how you would interpret your results.arrow_forwardThe following statements about the chi square test are correct. (Read each statement carefully. Select all of the statements below that are true (that you agree with). Leave any statements that are false (that you do not agree with) un- selected.) The null hypothesis infers that chance alone cannot account for the differences between observed and expected data. The null hypothesis infers that observed values are close enough to expected values. The lower the overall chi square value, the more likely the null hypothesis will be accepted. The higher the probability range associated with the overall chi square value, the more likely the null hypothesis will be rejected.arrow_forward
