Complete Research Methods Presentation

Hi all, this is my very nearly completed research methods presentation, containing 122 slides of detailed description of all research methods. The only thing not included is the section on reporting psychological investigations.

In the section on inferential tests, notes about the use of these tests is written in bold aqua.

The goals of science
Science offers a method of
distinguishing what is true
and real from what is not.
All scientific investigation
involves a detailed
examination of the subject
matter that is being studied
and this is done in a
systematic and objective
way.
Psychological science has
four key objectives:
Description
Understanding
Prediction

Here's a taster:

Description and
understanding
The first step towards understanding and explaining behaviour is
to describe it accurately. Detailed and unbiased observation is a
key link between the real world and more abstract scientific
ideas; it enables psychologists to be clear about the nature of
their subject matter and to describe specific phenomena, which
can later lead to possible explanations.
The next step is to develop our understanding to explain how and
why it occurs. Psychologists usually start by deriving a
hypothesis from a theory and then gather evidence to see
whether the hypothesis, and thus the underpinning theory, is
supported.
As a first step in testing explanations of phenomena, researchers
look for patterns and trends in the data they collect. If the
analysis of the data suggests a degree of certainty, then they can
be more confident about their explanation. If this is not the case,
then alternative explanations may need to be provided.

Prediction and control
After describing and attempting to explain a particular aspect of
behaviour, psychologists will usually try to predict when that
behaviour is likely to occur.
For example, we know that lacking a sense of control over aspects of
our life is associated with stress symptoms such as migraine and
gastric ulcers. We might therefore predict that people whose work is
monotonous, repetitive and regulated by others would be more likely
to have high rates of stress and absenteeism than people whose job
allows them more freedom to organise their work. Specific
predictions, such as this, can be tested.
Finally, scientists aim to control or modify a specific phenomenon by
manipulating the factors that cause it. In certain circumstances, it may
be desirable to modify behaviour.
Prediction and control are particularly important for applied
psychologists who use psychological knowledge and theories to bring
about improvements in many aspects of people's lives.

Great resource!! Lots of slides but all very informative! Covers all aspects of the spec in detail bar the last two points: 'Analysis and Interpretation of qualitative data' and 'Conventions of reporting on psychological investigations'. Apart from that it is brilliant!
