A researcher is interested in studying the effects of altitude on cognitive performance (e.g., perception, memory, problem solving, etc.). The researcher finds a group of experienced mountain climbers (n = 10) who volunteer to participate in the study. All of the climbers are tested at three different altitudes—at sea level (in the researchers’ laboratory at the University of California, San Diego), at the base camp (9,000 feet above sea level), and at 23,000 feet above sea level (at the peak of Mt. Denali in Alaska). At each location, the climbers perform a memory task (remember a list of 16 non-words like “biv”), and the accuracy of their memory is recorded (i.e., # of correctly recalled words). a. pls name the independent variable, dependent variable, levels of the IV, and the type of experiment design of this study (i.e., b/w- or w/i-subject design ) b. on what level of measurement is accuracy of memory assessed? (i.e., is it on nominal, ordinal, interval, or ratio?

An educational psychologist is interested in whether using a child’s own name in a story affected attention span while reading. Six children were randomly assigned to read a story under ordinary conditions (using common and generic names). Five other children read versions of the same story, but with each child’s ownname substituted for one of the children in the story. The researcher measured the amount of time (in minutes) each child spent reading the story. The results are shown in the following table. Does including the child’s namemake any difference in attention span? Test the hypothesis at an alpha set to .05, following these steps: a) write the null and alternative hypotheses; b) determine the critical value(s); c) draw the comparison distribution with rejection region(s) shaded; d)use the correct formula to compute the test statistic; e) state the statistical decision; f) state a brief conclusion.
Do people feel hungrier after sampling a healthy food? The authors of a consumer research paper carried out a study to answer this question. They randomly assigned volunteers into one of three groups. The people in the first group were asked to taste a snack that was described as a new health bar containing high levels of protein, vitamins, and fiber. The people in the second group were asked to taste the same snack but were told it was a tasty chocolate bar with a raspberry center. After tasting the snack, participants were asked to rate their hunger level on a scale from 1 (not at all hungry) to 7 (very hungry). The people in the third group were asked to rate their hunger but were not given a snack. The data in the table are consistent with summary quantities given in the paper (although the sample sizes in the actual study were larger).

Researchers investigated factors that influenced how much people like each other based on first meeting. They were particularly interested in the effects of eye-to-eye contact and smiling. They collected data from 20 participants. Each participant was asked to wait in a small room while the experimenter went next door, ostensibly to gather the materials needed for the study. While the participant was waiting, a confederate of the experimenter entered the room and sat in a chair facing the participant, and asked "Are you waiting for the experiment?". Immediately after asking the question, the confederate smiled at, and/or looked directly into the eyes of, the participant. This was done in four conditions: for five participants the confederate smiled and looked into the participant's eye, for five participants the confederate smiled but did not look into the participant's eye, for five participants the confederate did not smile but did look into the participant's eyes, and for five…

Which of the following is the best description of the experimental design? A therapist wants to study the effects of yoga and meditation on stress relief. She has 60 volunteers who experience varying levels of stress. She believes that the volunteers' professions could have an effect on the results. A preliminary survey reveals that 22 of the volunteers are in high-stress professions. The therapist randomly assigns 11 of these subjects to practice yoga and the remaining 11 to practice meditation. Nineteen of the other 38 volunteers are randomly assigned to practice yoga and the remaining 19 to practice meditation. Before the experiment begins, all the O observational study matched pairs design randomized block design completely randomized design participants will be asked to rate their stress levels on a scale of 0 to 10, with 0 representing "no stress" and 10 representing "highest level of stress." At the end of one month, the subjects will be asked to rate their stress levels again.…
A psychologist studied the alcohol consumption patterns of people in two age groups. One group consisted of people aged 21 to 35, and the other consisted of people aged 36 to 50. The psychologist interviewed random and independent samples from each group. She assigned a score from 0 to 100 to each individual (a score of 0 meant no alcohol consumption) according to factors such as the frequency and the amount of alcohol consumed. The results from the study are summarized below.
Is it a good idea to listen to music when studying for a final exam test? Does it matter what music you listen to? A researcher conducted a study. He worked with two independent samples, a random sample 1 of 44 students who were asked to listen to music by Mozart and another random sample 2 of 97 students who were asked to listen to Pop music while attempting to memorize objects pictured on a page. They were then asked to list all the objects they could remember (memory score). Here are the summary statistics for each group: the sample means are ¯x1=10.5x¯1=10.5 for sample 1 and ¯x2=9.5x¯2=9.5 for sample 2. Suppose that the population standard deviations are σ1=1.5σ1=1.5 and σ2=1.8σ2=1.8 are available. Could the researcher claim at a 4% level of significance that on average, there is no significant difference in memory score depending on the type of music students listen to? Use the zz-test for two independent samples and the formula,…
Do people feel hungrier after sampling a healthy food? The authors of a consumer research paper carried out a study to answer this question. They randomly assigned volunteers into one of three groups. The people in the first group were asked to taste a snack that was billed as a new health bar containing high levels of protein, vitamins, and fiber. The people in the second group were asked to taste the same snack but were told it was a tasty chocolate bar with a raspberry center. After tasting the snack, participants were asked to rate their hunger level on a scale from 1 (not at all hungry) to 7 (very hungry). The people in the third group were asked to rate their hunger but were not given a snack. The data in the table are consistent with summary quantities given in the paper (although the sample sizes in the actual study were larger). Find the test statistic and P-value. (Use technology. Round your test statistic to two decimal places and your P-value to three decimal places.)…
Professor Wonka is interested in whether candy influences children's mood. One group of children is recruited to be part of an experimental group, and another group of children is recruited to be part of the control group. Participants in the experimental group each eat 1 candy bar and then report on their mood on a self-report questionnaire. Children in the control condition do not eat anything before reporting on their mood. Here are the data from the two groups: Experimental (candy) group 15 18.3 94.6 n= M= SS= Control group 17 14.5 112.8 Calculate the effect size in terms of the n= M= SS= proportion of variance accounted for (r-).
