I have two-separate assignments that I need done by this Saturday. Both assignments are very-short in length, so the payout will not be that high. I am possibly looking for one-individual tutor to help me through this class. Please, serious inquiries only. I also prefer a tutor that knows about statistics, not just a general idea of Psychology. The assignments are posted below:

Assignment # 2:

Time to Practice: Week 1

Complete both Part A and Part B below.

Part A

Some questions in Part A require that you access data from Statistics for People Who (Think They) Hate Statistics. This data is available through the Textbook Resources link.

If you paste in SPSS output, highlight the required answers to the question.

  • By hand or using SPSS, compute the mean, median, and mode for the following set of 40 reading scores:
  • Compute the means for the following set of scores using IBM® SPSS® software. The data sets can be found through the Sage Materials in the Student Textbook Resource Access link, listed under Academic Resources. The following set of scores is saved as Ch. 2 Data Set 3. Copy and paste the output from IBM® SPSS® into this worksheet. You will have a mean for Bed number and also for infection rate.
  • You are the manager of a fast food store. Part of your job is to report which special is selling best to the boss at the end of each day. Use your knowledge of descriptive statistics and write one paragraph to let the boss know what happened today. Use the following data. Do not use IBM® SPSS® software to compute the statistics needed; rather, do it by hand. You may check your work in SPSS after you compute it.
  • Suppose you are working with a data set that has some different (much larger or much smaller than the rest of the data) scores. What measure of central tendency (mean, median or mode) would you use and why?
  • Use IBM® SPSS® software to compute all the descriptive statistics for the following set of three test scores over the course of a semester. Which test had the highest average score? Which test had the smallest amount of variability?
  • This practice problem uses the data contained in the file named Ch. 3 Data Set 3. There are two variables in this data set. The data sets can be found through the Sage Materials in the Student Textbook Resource Access link, listed under Academic Resources. Using IBM® SPSS® software, compute all of the measures of variability you can for height and weight. Copy and paste the output from IBM® SPSS® into this worksheet.
  • Identify whether these distributions are negatively skewed, positively skewed, or not skewed at all and why.
  • For each of the following, indicate whether you would use a pie, line, or bar chart, and why.
