Description

I have three-separate Statistics assignments that I need help with, These are relatively short-assignments. Attached separately are some of the supporting documentation. The first assignment and third-assignment's are going to be the 2nd attachment. The second-attachment is going to be the first assignment. The last-two documents are going to be the data tables for the 3rd assignment.

Time to Practice: Week 2 PSYCH/625 Version 4 University of Phoenix Material Time to Practice: Week 2 Complete Parts A, B, and C below. Part A 1. Why is a z score a standard score? Why can standard scores be used to compare scores from different distributions? 2. For the following set of scores, fill in the cells. The mean is 74.13 and the standard deviation is 9.98. Raw score Z score 68.0 ? ? –1.6 82.0 ? ? 1.8 69.0 ? ? –0.5 85.0 ? ? 1.7 72.0 ? 3. Questions 3a through 3d are based on a distribution of scores with = 6.38. Draw a small picture to help you see what is required. a. b. c. d. and the standard deviation What is the probability of a score falling between a raw score of 70 and 80? What is the probability of a score falling above a raw score of 80? What is the probability of a score falling between a raw score of 81 and 83? What is the probability of a score falling below a raw score of 63? 4. Jake needs to score in the top 10% in order to earn a physical fitness certificate. The class mean is 78 and the standard deviation is 5.5. What raw score does he need? From Salkind (2011). Copyright © 2012 SAGE. All Rights Reserved. Adapted with permission. Part B The questions in Part B require that you access data from Using SPSS for Windows and Macintosh. This data is available on the student website under the Textbook Resources link. The data sets for problems 5 and 6 can be found through the Pearson Materials in the Textbook Resources link. The data is listed in the data file named Lesson 20 Exercise File 1.

She has demographic data on the participants’ gender (two categories), educational level (four categories), marital status (three categories), and community population size (eight categories). 5. Using IBM® SPSS® software, conduct a frequency analysis on the gender and marital status variables. From the output, identify the following: a. Percent of men b. Mode for marital status c. Frequency of divorced people in the sample 6. Using IBM® SPSS® software, create a frequency table to summarize the data on the educational level variable. Copy and paste the output from IBM® SPSS® into this worksheet. From Green & Salkind (2011). Copyright © 2012 Pearson Education. All Rights Reserved. Adapted with permission. Part C Answer the questions below in at least 90 words. Be specific and provide examples when relevant. Cite any sources consistent with APA guidelines. Question Answer What is the relationship between reliability and validity? How can a test be reliable but not valid? Can a test be valid but not reliable? Why or why not? What are the four different levels of measurement? Explain and provide examples. How does understanding probability help you understand statistics? Copyright © 2017, 2014 by University of Phoenix. All rights reserved. 2 First Assignment: Weekly Checkpoints provide you an opportunity to interpret results in the context of specific data before you complete worksheets and other assignments. Complete the Week 2 Checkpoint by responding to the following: •Emily is a fifth-grade student who completed a standardized reading test. She scored one standard deviation above the mean score. How does the normal curve help you understand what this means about how your child compares to other children who took the test? Explain how you determined your findings. How many children scored lower than your child? How many scored higher? Second Assignment: See Attached Document Third Assignment: (Data Tables 1 and 2 are listed in attached documents.) This assignment allows you to become familiar with importing Microsoft® Excel® (or some other type of data) into SPSS and using the Analysis tab (for frequencies). In actual research, the individual data points are entered into SPSS, but for the purpose of this course, you import data for your final project due in Week 6. You run frequency tables, not descriptive statistics, on all appropriate variables as designated in your data set. Note: Frequency tables are best used for nominal and ordinal variables. Select one of the provided data sets, or select your own. Import your data into IBM SPSS software, and run frequencies (frequency tables, not descriptive statistics) on all appropriate variables as designated in your documentation. Frequency tables are best used for nominal and ordinal variables. Summarize the results of the process in 45 to 90 words. Submit the IBM SPSS output and your summary to your instructor.
