topic 3 Flashcards
(19 cards)
research qn
outlines a specific scope for investigation related to topic
- little research
- many conclusions formed
hypothesis
- measurable statement consisting 2 or more variable
- definite conclusion
quantitative data
- can be measured
- close-ended qns ( limited responses)
qualitative data
-open-ended responses
probability sampling
- randomly selected
- removes bias
- greater chance of creating representative ( common ) sample
Simple random sampling
there is little known about the population under study.
probability sampling
Stratified random sampling
when the population clearly includes significantly different sub-groups.
probabilty sampling
convenience sampling
carried out in an ad hoc manner that is *most accessible to the researcher. *
non-probability sampling
Quota sampling
- takes into consideration factors
- selected to replicate the general structure of the population
non-probability sampling
likert scale
rating scale that presents a range of responses anchored by two extreme opposing positions.
ie. ( excellent to extremely poor )
ranking scale
items are compared with one another and ordered in preference by survey participants
count
total no. of times something occurred
percentage
data/total data x100%
ground level images
present a detailed part of an area
aerial images
present spatial distribution and patterns over the whole area.
word clouds
Colour-coded quotations are useful when researchers are analysing a large body of texts. The colours used help to categorize and present important findings for their research, whereas word clouds have words that
- appear in different colours and sizes
- signal their relative importance.
- Quantitative data
- Qualitative data
1 is collected to identify patterns and trends
2 is collected to examine patterns and trends
Qualitative then quantitative
Collected to make observations then verify the observations
Non probability sampling and when is it used?
Non random, researchers decision. Biased.
When it is unecessary or conducted quickly due to time limitation.
