Questions for Assignment: Provide Outcomes with Brief Explanatory Comments
The central question of this study is: Are faculty members of an undetermined HBCU prepared to the
conversion of all classes to online delivery due to a pandemic emergency?
The sample of 361 cases responded to a survey at the start of term. There are some typical independent
variables such as Age, Gender and Faculty Rank; and there are two dependent variables: Faculty Attitude
about Technology (FACATT) and Faculty Knowledge about Technology (FACKNT). These two variables
have to be calculated out of some answers to the questions that scale format (numbered 1 to 5).
1. Provide table summaries and bar charts for the variables Gender, Age, Faculty Rank, Use of
Office Computer and Use of IT in Class. What is your conclusion?
2. Create FACATT = MEAN (Q31A1 TO Q31A12); and FACKNT = MEAN (Q31B1 TO Q31B4). Label
these variables appropriately.
3. Do the basic Descriptive Statistics indicated above (1.1) for FACATT and FACKNT. What is your
4. Use the Frequencies command to get a histogram of FACATT and FACKNT, no tables. What can
you tell about the shape of both distributions?
5. Let us analyze if these two variables were measured in a reliable manner. Do Scale?Reliability
Analysis for FACATT, items Q31A1 TO Q31A12; and for FACNT, items Q31B1 TO Q31B4. What is
6. Correlation Analysis: Do a Bivariate Correlation Coefficient, for Age, Faculty Rank, Teach Time,
FACATT and FACKNT (independent and dependent variables). What is your conclusion?
You will upload the following:
– Word document converted to PDF with the tables and graph outcomes and brief explanation,
maximum three sentences for each outcome table or graph.
Criteria for Comments to Tables and Graphs:
1. Comments must be present, if missing the points per question are discounted 40%
2. Comments refer to the meaning of the statistic, not simply reproduce the statistics in the
table; for instance, Mean height of females is 62.5, which is lower than the US Average
(64.0). Instead of simply stating Mean height of females is 62.5.
3. If the outcome refers to test of hypothesis, the comment must indicate clearly the null
hypothesis being tested and whether to reject or fail to reject the null hypothesis
4. In addition the comment would mention the alpha or Sig. level used in the test; for instance:
not significant at Alpha = 0.05, not significant at Alpha = 0.01 but significant at Alpha =
0.05, or simply significant at Sig. 0.01 or better.
