EDLM40 Data Analysis & Research Methods
PART II
General instructions
This part of the assessment is worth 50% of the module. It is divided
into four parts of equal weighting. You should attempt all parts. The total
word limit is 2000 words – excluding the contents of Tables and Figures.
Submit Part II as a separate file via TurnItIn in the module Sunspace.
Use Tables and Figures to support your interpretation of the data. In
interpreting the data be sure to describe the results fully in words i.e.
Tables, Figures and descriptive statistics must be fully explained.
Questions A, B, and C require you to use of a statistical test. For these
questions you should state:
- the Null Hypothesis
- a brief explanation for your choice of test
- the results of the tests reported in an appropriate format (i.e. not
material cut-and-paste from SPSS output)
- an interpretation of the findings.
There is no need to conduct statistical tests for Question D. Your
answer for this question should state:
- the Null Hypothesis and statistical test that you would apply to
answer each question
- a brief explanation for your choice of test
The statistical tests in Questions A, B and C may be carried out using a
statistical package (e.g. SPSS) OR by hand.
If you use a statistical package you should cut-and-paste the computer
generated output and include this in your report. You MUST then extract
the relevant information from this output and present it in an appropriate
format in your answer. You must be careful to demonstrate that you
understand the results of the tests performed.
If you elect to do the calculations by hand, workings for each step in the
calculations should be shown in your report. Remember that you must
demonstrate that you understand the results of the tests performed.
There is NO need to refer to the wider academic literature (e.g. on health
and safety in the workplace, gender discrimination etc.), but DO cite any
statistical textbooks or computer package used.....
