Reasons that other people need to know research methods: WHO does the study is important, just as the "method". For example, many people distrust studies done by a controlling company because a study's results can affect the marketability of a product or affect financial stock sales.
A pharmaceutical company that tests its own medications. A major manufacturer who submits water studies while hiding that the plant has run-off of highly toxic substances.
Accurate research should be able to be replicated or duplicated. Many times, "research" is simply "claims" without good research. The number studied is important! The bigger the sample, the more accurate the results. For example, a large medical study of women showed that yearly mannograms do not decrease the incidence of breast cancer. Although people are debating the results, this study has more validy than a study done on say, 50 women.
Because I only studied 2 people, my "research" and "data results" is very misleading! A "blind study" in medicine often has more validity. It means the study group did not know key details; sometimes the research doesn't know which group in a study receives medication.
A "double blind" study means both the researcher and the participants did not know -- like which patients took the real medicine or took a placebo. A "double blind" ensures that the researcher cannot impose his ideas onto the results, like, if Dr. Smith believes Drug RXRX will improve liver function, he won't unknowingly interpret results to fit his ideas.
In Marketing studies, it is important to know whether the "study" was truly a "study" or if it was simply done by "consumer surveys". It is also important with all studies to know whether participants were paid money, or if they got some other type of reimbursement. Online surveys are not "studies" but surveys that might be influenced by how much a person gets paid. If the "pay" is only 25 cents, the responding person may just click-click whatever answers, just to finish the questions fast-- but not accurately.
This is not a complete list of why readers should know the specific research methods used, but it gives you an idea of why this knowledge is important. What are the strengths and weaknesses of correlational methods of psychology?
The strengths of correlation methods is that it allows researchersto examine relationships between two variables. The disadvantage isthat it is not valid to assume that the relationship between twovariables will apply to all similar variables in general. What are the examples of historical method in research? The historical method in research is used by historians to get acorrect account of events in order to document the past.
Examplesof historical research include relics, eyewitness testimony,indirect witness testimony, and oral tradition passed down throughthe generations. What are parameters in research methods? Parameters in statistics is an important component of any statistical analysis. In simple words, a parameter is any numerical quantity that characterizes a given population or some aspect of it.
This means the parameter tells us something about the whole population. Example of descriptive method of research? In this research, you would want to show as much information aspossible. Include all of the details along with pictures and chartsif applicable. What is experimental method of Marketing research?
Is a research technique in which a researcher observes the results of changing on or more marketing variables while keeping other variables constant under controlled conditions. The only bad studies I am aware of are those done for profit orwithout the appropriate conditions for objectivity.
What is the Survey method of research in psychology? A survey is a data collection tool used to gather information about individuals. Surveys are commonly used in psychology research to collect self-report data from study participants.
A survey may focus on factual information about individuals, or it may aim to collect the opinions of the survey takers. A survey can be administered in a couple of different ways. In one method known as a structured interview, the researcher asks each participant the questions.
In the other method known as a questionnaire, the participant fills out the survey on his or her own. Surveys are generally standardized to ensure that they have reliability and validity. Standardization is also important so that the results can be generalized to the larger population.
Advantages of Using Surveys. Surveys allow researchers to collect a large amount of data in a relatively short period of time. Surveys are less expensive than many other data collection techniques. Surveys can be created quickly and administered easily. Surveys can be used to collect information on a wide range of things, including personal facts, attitudes, past behaviors and opinions.
Disadvantages of Using Surveys. Poor survey construction and administration can undermine otherwise well-designed studies. The answer choices provided on a survey may not be an accurate reflection of how the participants truly feel. While random sampling is generally used to select particpants, response rates can bias the results of a survey.
Types of Survey Data Collection Surveys can be implemented in a number of different ways. Chances are good that you have participated in a number of different market research surveys in the past.
Some of the most common ways to administer survey include: Mail - An example might include an alumni survey distributed via direct mail by your alma mater. Telephone - An example of a telephone survey would be a market research call about your experiences with a certain consumer product. Online - Online surveys might focus on your experience with a particular retail, product or website. At home interviews - The U.
Census is a good example of an at-home interview survey administration. What are the advantages and disadvantages of correlational research? Correlational research is beneficial because it helps researchers to see the relationship between two or more things.
It helps narrow down possible causes for diseases, behaviors, etc. For example, discovering the correlation between smoking and cancer has led to much research and literature informing individuals who smoke of their increased chance of developing cancer. However, correlational studies can be disadvantageous as well. It is important to know the distinction between "correlation" and "causation.
Just because two factors are correlated does not mean that one caused the other. For example, we may see that there is a positive correlation between drowning and ice cream sales that is, the number of drownings increases as the number of ice cream sales increase. Does this mean that ice cream causes drowning? However this is a disadvantage if everybody in the family prefers slightly different ingredients in their meal, since you cannot easily prepare stews separately to everybody's liking.

Research Methods › Correlation. Correlation. Saul McLeod, published Correlation means association - more precisely it is a measure of the extent to which two variables are related. If an increase in one variable tends to be associated with an increase in the other then this is known as a positive correlation. An example would be height Author: Saul Mcleod.
Correlational research is a type of nonexperimental research in which the researcher measures two variables and assesses the statistical relationship (i.e., the correlation) between them with little or no effort to control extraneous variables.
Case studies, surveys, naturalistic observation, and laboratory observation are examples of descriptive or correlational research csample.ml these methods, researchers can describe different events, experiences, or behaviors and look for links between them. The correlation is one of the most common and most useful statistics. A correlation is a single number that describes the degree of relationship between two variables.
