Interpret it as "small", "medium" or "large". r2=-3.642/-3.642-12 =-13.23/-25.23 Page 4 of 7 PSYC 510 = 0.5 Elisabeth Waterbury 12) Write an APA-style Results section based on your analyses. Remember to use complete sentences, include the statistical notation, effect size, confidence -1 Is this small, medium, or large? interval, and include a decision about the null hypothesis. If it is significant, state13) What is the I obtained from your SPSS output? Using your table in the Appendix of your e-book, determine the critical t value for this study. Clearly identify the t obtained and the t critical values below. Describe how the critical value can be used to determine whether a 3 obtained value will result in a rejection of the null hypothesis (i.e. that it is signicant). rm = -3.64 \"Van\" , , Elisabeth Waterbury 1 How would you use this Part III: Cumulative information when deciding whether to reject the null? These questions can be related to anything covered thus far in the course. 14) Paste the appropriate SPSS output to analyze whether higher sensitivity to prejudice is related to lower self-regulation ability.

If the null hypothesis is not rejected, the specialist will deduce that inclination is connected with unfortunate self-guideline. The reality of t? matter is that inclination awareness isn't related with more fragile self-guideline 18) If you were to conduct this study, would you fully disclose the rationale to the participants beforehand? Why or why not? Use the APA Code of Ethics to justify your response (must cite at least one principle and/or code). ANSWER , Elisabeth Waterbury -2 That is a type 1 error. A type 2 error is concluding there isn't a significant effect, when in reality there is one. Research Scenario: According to some research, males have better spatial skills than do females; and according to other research, females have better reading skills than males. A student is interested in determining which gender performs better on a word-search puzzle (a puzzle in which words are hidden vertically, horizontally, and diagonally within an array of letters) since this type of puzzle involves both spatial and reading skills. A sample of males and females volunteer to participate and are given 10 minutes to work on a 50-word puzzle. The number of words correctly recognized is recorded for each subject, and the resulting data are as follows: Males Females 12 15 8 12 9 11 11 18 10 13 12 14 7 17 Create your SPSS data file to answer the questions below (remember that the IV is your "grouping variable" and will be represented with numbers in SPSS and your DV will be data entered in a second column.

MALE FEMALE GENDERResearch Scenario: In this fictitious scenario based on a study by Inzlicht and colleagues (2006), researchers examined whether sensitivitieso race-based prejudice is related to self- regulation abilities in Black college students. They predicted that higher sensitivity to prejudice is related to lower self-regulation ability. Black university students completed two surveys to measure self-regulation abilities and sensitivity to race-based stigma. Both surveys used Likert-based responses; data is provided below for the 12 students. Create an SPSS file to answer the following questions.
