You will need to use the R-program and show all hand calculations with your output fro any fucntion R
cannot handle!
The grading scheme is based on the following:
· use of R wherever possible
. an outcome is significant only if it has a probability less than .05
· with each question, indicate its number (e.g., Question #1), the written answer and the R output
(The R output must include the student’s data file name –see below). (Note: If
output are not placed after each question, it will not be marked)
· show all hand calculations with your output for any function R cannot handle
· use APA formatting (e.g., double spacing, 12 pt. font – Times New Roman, 1 inch margins) for all written answers a hard copy is required with single sided pages.
· the R output with each question will dictate the analysis you have decided to use and,
thus, must be consistent with the name of the test stated in the written section of your answer
· a complete answer must state the interest of the question, define the variables involved, describe the groups (if applicable), name the test used to analyse the data, report the statistical results – e.g., t(45) = 3.50, p < .05, and provide meaningful conclusions
The data for this assignment represent information from the 2016-2017 PSYC 3015 class on thoughts and behaviours regarding statistics. The data file (ASS1Fall2021) is attached. Save it to your
directory and rename it as ASS1BLEEOWN The ASS1Fall2021 file has
been managed. This file allows you to proceed and complete Assignment 1.
1. Write a formal report no longer than one page and one quarter pages (1 page plus 4 lines)
describing the participants of the PSYC 3015 class and variables assessing general/statistical thoughts and
behaviours. Remember to generate the appropriate descriptive statistics for the type of measurement scale
for each variable. Include an APA table illustrating the descriptive statistics for the continuous variables only.
2. Based on the 2007-08 academic year, the frequency distribution of who
predominantly paid for one’s education were as follows:
26% reported ‘myself’
26% reported ‘my family’
42% reported ‘student loans’
6% reported ‘other’
Does the frequency distribution of who predominantly pays for one’s education (EDUC) for our
PSYC 3015 2016-2017 students significantly differ from the frequency distribution of that
observed in 2007-08?
3. The median-split method was used to split SCST into 2 groups and a new variable was created
in your data set called SCSTGR. Those participants with SCST ranging from -56.00 to 11.32 were
place in the “Low” group and those with SCST scores ranging from 12.33 to 86.40 were placed in the
“High” group.
Determine whether students who are high scoring in general resourcefulness (SCST) differ significantly in their anxiety toward statistics at time 1 (ANXIETY) in comparison to those who are low scoring
in general resourcefulness. In addition to performing and analyzing the appropriate statistical test,
report and interpret both the 95% confidence interval and power.
