Question Answered step-by-step 1) A researcher is interested in the effects of room color (yellow,… 1) A researcher is interested in the effects of room color (yellow, blue) and room temperature (20, 24, 28 degrees Celsius) on happiness. A total of 120 university students participated in this study, with 20 students randomly assigned to each condition. After sitting for 30 mins. in a room that was painted either yellow or blue, and that was either 20, 24, or 28 degrees, students were asked to rate how happy they felt on a scale of 1 to 15, where 15 represented the most happiness. The mean happiness scores are as follows:temperature room color happiness20 yellow 1224 yellow 1028 yellow 620 blue 424 blue 428 blue 41A) Place the data into the cells of the matrix and determine the row and column means (a hand- drawn matrix is fine).1B) Draw a fully labeled line graph of the results (a hand-drawn graph is fine).1C) List each significant effect and after each one, describe what the effect is telling us about how temperature and color affected happiness. (For the purpose of this exercise, assume that a difference of “1” between any of the row or column means is a significant difference. Also, if the data or graph seems to indicate an interaction effect, consider it as being a significant interaction.)1D) If any of the above effects should take precedence, indicate which effect(s). (If they are of equal importance, simply indicate so.)1E) What is the specific name given to this type of design?1F) If you were to conduct a study on the effects of temperature and room color on happiness AND on anxiety, how would you present these findings in a line-graph format? You can either draw a diagram or provide a short written description. 2A) Suppose you found a correlation coefficient of r = +1.23 between “grade on a test” and “amount of sleep the night before”. How would you describe this relationship?2B) Would it generally be preferable to have a correlation coefficient of r = +.52 as opposed to r = -.52?2C) If the correlation coefficient between “number of minutes studied” and ” test grade” isr = -.64, what is the coefficient of determination?2D) What is the coefficient of determination telling you about the relationship between these two variables (in 2C)?2E) If you suspect that anxiety underlies an apparent correlation between “fidgeting” and “stuttering”, what procedure might you use to determine if your suspicion is correct? (A description of the procedure is not necessary). Social Science Psychology PSYC 2030 Share QuestionEmailCopy link Comments (0)
