For each of the following FRQs, start a timer for 15 minutes and try to answer each of them in that time. You can use your notes, book, google. You cannot use other people to help you. This is the time to see how you might do on the 2nd FRQ for the AP exam.I have separated them by pages so you can avoid seeing the next question.I would suggest setting a timer on your phone or computer or microwave and then starting each question. Consider keeping track of the time for each question below. If you can’t finish in 15 minutes, please still finish the question but try and self-assess what slowed you down. Good luck!Question 1 ____________Question 2 ____________Question 3 ____________Submit answers to all three questions in the same document on turnitin by Thursday 4/23 at 10:45am.1)Researchers conducted a study in which 10 participants went to a laboratory around dinnertime. The researcher assigned students to one of two groups by flipping a coin. Half of the participants were assigned to a “large bowl” group, and half were assigned to a “small bowl” group. By luck of the draw, 4 men and 1 woman were in the “large bowl” group, and 4 women and 1 man were in the “small bowl” group. Participants were told they could take as much pasta as they wanted from a serving bowl in the middle of the table, which was kept at a nearly full level. . In order to determine how much food each participant actually ate, the researchers measured the weight of the food that each participant took, as well as the amount that the participants left in their bowls. The amount of pasta (in grams) each participant ate is shown in the table below:Determine the median of the “large bowl” group.Describe the research technique used to determine the groups.Explain how the data illustrate differences in variability between the groups.Explain a how a design flaw in this study could be corrected. 2A psychologist conducted a study at her home during an annual activity of children wearing masks and going door-to-door receiving candy. Some of the children arrived alone, while others arrived in a group. Over the course of the night, the psychologist asked half of the children to remove their masks when they arrived at her door. The remaining half kept their masks on. The psychologist told every child to take only one piece of candy. She then went inside the house, leaving the bowl of candy outside. This gave children the opportunity to take additional candy. The psychologist measured the percentage of children who took additional candy. The psychologist’s hypotheses were that children would take more candy when they were alone and that children would take more candy when they were masked. The results are shown in the graph below; assume all differences are significant.Identify the operational definition of the dependent variable in this study. Explain how the data support or do not support each of the psychologist’s hypotheses.Explain why the psychologist cannot generalize her findings to all children.Explain why the study is not a naturalistic observation.3Researchers dropped 200 identical wallets on sidewalks at a large university. Each wallet contained the name and address of the owner and either a photograph of a baby, a photograph of a puppy, a photograph of a young family, a photograph of an older couple, or no photograph. The researchers hypothesized that the type of photograph left in the wallet would influence the rate of return. The wallets with a photograph of the baby and the wallets with the photograph of the puppy were left early in the morning, the wallets with the photographs of the young family were left in the afternoon, and the wallets with wither no photograph or a photograph of the older couple were left in the evening. Eighty-four of the 200 wallets (42%) were eventually returned to the owner, as shown below. Identify the following aspects of the study as described above:Control ConditionDependent VariableConfounding Variable.A survey was conducted in which individuals were asked “Would you return a lost wallet that you found?”. Use social desirability bias to explain where the percentage of the individuals who answered “yes” to this survey question would be higher, the same, or lower that then overall return rate (42%) in the study above. ................
