Which sampling technique is appropriate in this particular
research? Explain your Answer. Solution:Types of sampling Non-Probability
and Probability and Probability sampling types are these
- Simple random sampling
- Systematic random sampling
- Stratified random sampling
- Cluster sampling
- Double sampling
A stratified
sampling approach is most effective in this case study especially.
Reasons/conditions for this sampling:
1. Variability
between strata is maximized
2. Variability
within strata is minimized
In statistics, stratified sampling is a method of sampling from a
population.
So we choose one sampling
techniques in the above probability sampling‘s sort which is stratified random
sampling. We use probability sampling as researcher must classify definite
sampling element to include in the sample. As a researcher when we conduct a
study on the voting behavior of the people in the previous general elections in
Punjab. Firstly according to the stratified
random sampling, we make many strata of the population element.
Reason
to choose stratified random sampling:·
Stratification is usually more efficient
statistically
·
Stratified random sampling provides the
assurance about the samples
·
Enable to different research procedure in
different strata
·
Reduces random sampling error
·
Provide adequate data about the various sub
population
This case study
shows that the research bases on the past data but its focal point the people
such as their behavior, beliefs, attitudes, and their sentiments all of these
elements show that in this study. By using the stratified technique two methods
can be helped in this case “Qualitative method" is suitable for research,
because in the opinion of MR max Weber Qualitative approach is the behavioral
sciences. The aim is to explain behavior and attitudes by developing a
discussion. Qualitative researchers aim to collect deeply and fully
understanding of human behavior and the reasons that administrate such
behavior. It based on the specific area that is Punjab
through using this technique getting people to talk through in their own words
how they see a particular idea.
Secondly Target population is the suitable method of
sampling because it marks to the specific people from entire population just
like Punjab in given assignment file and
chooses a specific topic just like elections rating in assignment file.
According to this study we can go to rural and urban areas for asking people’s
opinion about elections. Target population is also called survey research.
Through this technique we can make sure people behaviors on elections directly.
Target population is entire group of specific population basics related to the
research Topic.
2) Suggest
the appropriate data collection tool that can be used by the research organization.
Give the solid rationale for your answer. Solution:·
Survey / interview schedule
·
Questionnaire
·
Observation
Firstly: Most
appropriate tool for data collection can be survey especially for these types
of researches. In the above scenario, gave the information that rural voters
are greater than urban voters. In that situation, we know that in rural area
less educated people it might be possible that they faced some difficulties in
questionnaire so interview schedule is the best tool and at the spot we also
check attitude, belief of the respondent about the election. Survey is a tool
for data collection in which researcher asks the questions and makes face to
face interviews or telephonic interviews to respondent. Target population as
sampling techniques and Survey as data collection tool is a very combination in
research. One reference is used sample survey which emphasizes that the purpose
of contacting respondent is to obtain a representative sample of target
population. In the survey researcher can use different type of questionnaire as
per situation it can be through electronic or may be physically as well.interview schedulebecause list question remains in the hand of the interviewer who
ask question from respondent, or get
direct response form the people on the sport
records all type of responses
of respondent
.
Secondly:In this case researcher is using available information tool so
observation as we know that the research is based on the larger scale and based
on the previous data so for such type of research can be used the available
information, has already been collected by others, observation is a technique,
is involved systematically selecting watching and recording behavior. One can
also use this tool but we know already that this method is based on the small
scale so it becomes very difficult to conduct observation of each individual so
according to my point of view the available information is perfect.
