Quantitative
• Inferential – form a database from which to infer characteristics or relationships of population
• Experimental – greater control over the research environment, some variables are manipulated to observe their effect on other variables
• Simulation – construction of artificial environment
Qualitative
• It is concerned with subjective assessment of attitudes, opinions and behaviours
• It is a function of researcher’s insights and impressions
• Focus group interviews, projective techniques, depth interviews are used
Steps in Research Process
• Formulating the research problem
• Extensive literature review
• Developing of working hypotheses
• Preparing the research design
• Determining sample design
• Collecting the data
• Execution of the research design
• Analysis of data
• Hypothesis testing
• Generalization and interpretation
• Preparation of the report
1. Formulation of the Research Problem
• First decide the general area of interest and then narrow it down
• State the problem in a broad general way and then the ambiguities
• Check the feasibility of a particular solution
• There are two steps involved-
• Understanding the problem
• Rephrasing it into meaningful terms
• Discuss with people, help of guide
• Be specific in stating the problem
2. Literature Review
• A brief summary of the problem to be written – synopsis
• For this extensive literature survey to be done
• Academic journal, conference proceedings, reports, books
4. Preparing the Research Design
• Prepare a conceptual structure within which research would be conducted
• Function of research design is to provide for the collection of relevant evidence within minimal expenditure of effort, time and money
• Research design includes –
• Means of obtaining information
• Availability and skills of the researcher
• Explanation of the way in which selected means of obtaining information will be organized
• Time available for the research
• Cost factor relating to research
5. Determining sample design
• All the items under consideration in any field of inquiry constitute a universe or population
• We select only a few items from the universe for our study purposes
• The items so selected constitute what is technically called a sample
• Samples can either be probability samples or non-probability samples
• Probability – simple random, systematic, stratified, cluster/area
• Non – probability – based on convenience, judgement, quota
6. Collecting the data
• By observation, Through personal interviews, Telephone interviews, By mailing questionnaires, Through schedule
• Researcher should select one of these methods of collecting the data taking into consideration the nature of investigation, objective and scope of the inquiry, financial resources, available time and the desired degree of accuracy
7. Execution of the project
• Project should be executed in a systematic manner and in time
• A careful watch should be kept for unanticipated factors
• Steps should be taken to ensure that the survey is under statistical control so that the collected information is in accordance with the pre-defined standard of accuracy
9. Hypothesis testing
• Do the facts supports the hypotheses or they happen to be contrary?
• Statistical Test like chi square test, t –test, f – test are done
• Hypothesis testing will result in either accepting the hypothesis or rejecting it
11. Preparation of the report or the thesis
• Layout of the report should be –
• Preliminary pages - title, acknowledgement, foreward, content page,
• Main text – introduction, findings, conclusions
• End matter – appendices, bibliography

The definition of the experimental method is a scientific method message to confirm cause-and-effect relationships by introducing independent variables and observing their effects on dependent. “An example of experimental method, suppose a researcher wants to study the effect of drug A on subjects’ alertness. He divides 100 subjects into two groups of 50, and experimental group and a control group. He dissolves drug A in saline solution and injects it into all the subjects in the experimental group. He then gives all the control group subjects an injection of only saline solution. The independent variable in this case is drug A, which he administers only the experimental group. The control group receives a placebo: the injection of saline solution. The dependent variable is alertness, as measured by performance on a timed test. Any effect on alertness that appears only in the experimental group is caused by the drug. Any effect on alertness that appears in both the experimental and control groups could be due to the subjects’ expectations or to extraneous variables, such as pain from the injection.”…

Cause and effect experimental research involves a situation where a researcher manipulates a variable called an independent variable. Once that is done, he evaluates another variable called a dependant variable and checks to see if it reacts to the manipulated independent variable. If the dependant variable is reacting to the independent variable in a predicted way, than the researcher can conclude that the independent variable is the cause of the change of the dependant variable. This is the process of a cause and effect experimental research test. In a field experiment, subjects are observed in their natural outdoor environment so that researchers can study their behavior. Most of the time, the subjects are not aware of the researchers and so usually the conclusions are mostly accurate. For example, researchers may follow lions and research how they live, eat, breed and also migrate in order for them to stay close behind on their prey. As long as the researchers are not interrupting the lion’s routine, their findings should be highly accurate. The drawback to this experiment is that the researchers have little to no control of the experiment if something happens. The last experiment is a laboratory experiment. This is where a subject is put in a controlled environment so that the researcher can manipulate the setting and see if it causes any reaction in the subject. The advantage to this research is that the researcher has a high amount of control of the setting so that he or she can manipulate the environment and way they see fit in order to get a response from the subject. One example could be putting a subject in a empty room and administer different drugs to him to see what would be the results. Since the room is empty and nothing can interfere with the subject, the researchers can monitor the subject closely and record accurate readings since there are…

Experiments (or randomized controlled trials [RCTs]) involve manipulation (the researcher manipulates the independent variable by introducing a treatment or intervention); control (including use of a control group that is not given the intervention and represents the comparative counterfactual); and randomization or random assignment (with people allocated to experimental and control groups at random to form groups that are comparable at the outset).

Functions of research The overall function of research is to gather information on subjects wherein people have little knowledge about. It is to develop and evaluate different concepts, practices and theories, evaluate different methods and obtain knowledge to solve different issues/problems. Some other functions are “identifying needs, highlighting the gaps in provision, planning provision informing policy or practice, extending knowledge and understanding, improvising practice, aiding reflection, allowing progress to be monitored and examining topics of contemporary importance”-(BTEC Health and social care level 3 book 1) Identifying needs…

The research design according to (Hagan,2010), is the type of experimental or non-experimental approach, studies of a group (or groups) at one time or over a period of time, and use of control groups, (p. 19). Then there is the collection of data, this is the third step in the research process. The method of which data is collected could be by observing a particular person, place, or thing as well as the reanalysis of any past data,…
