Shevelev Vladimir In any organization, managers at all levels need accurate and timely information for managerial decision making. Whether the decisions made are at technical, tactical, or strategic levels, good, accurate, and timely information always leads to a better decision. Gathering of information is done through a sound and scientific research process. Each year organizations spend enormous amounts of money for research and development in order to maintain their competitive edge.
Experiment The experiment is a type of research that has been used frequently by natural scientist. The goal of an experiment is to examine the probability of a change in an independent variable causing a change in another, dependent variable Hakim Instead of research questions, an experiment uses hypothesis predictions.
There are two kinds of hypothesis in an experiment: Null hypothesis - which predicts that a significant difference or relationship between the variables does not exist The alternative hypothesis - which predicts there is a relationship or Summary business research methods When performing an experiment, the null hypothesis is tested statistically.
The null hypothesis will be accepted when the probability that there is no statistical difference is greater than a prescribed value most of the times 0.
In this case the alternative hypothesis will be rejected. There are various experimental designs: Classical experiment — a group of participating people is selected and randomly assigned to either a control or an experimental group.
The experimental group will test a manipulation or intervention storing and in the control group no such intervention is made. Because the control group is influenced by the same external influences as the experimental group any changes to the dependent variable will have to be caused by the intervention.
Quasi experiment — also uses an experimental and control group, but the participants will not be randomly assigned to a group.
Matched pair analysis is when a participant in a control group will be compared to a participant in the experimental group based on matching factors such as gender, age, occupation etc.
Every participant will be subject to an intervention of the independent variable. Before the intervention, all participants will be observed, a pre-intervention, to establish a baseline or controlafter which a planned intervention of the independent variable and observation and measurement of the dependent variable will follow.
This research design requires much less participants than others, but the side effects may be that the participants become tired or familiar with the experiment. Internal validity is the extent to which the findings of the experiment can be attributed to the interventions instead of any flaws in the research design such is the case with a laboratory experiment.
External validity is a lot more difficult to establish when conducting field-based research. Survey This research strategy is usually associated with the deductive research approach.
It is often used for exploratory and descriptive research. Because most surveys use questionnaires it is easy for people to understand and to explain. This is the reason why this kind of research design is so popular. Besides through questionnaires, data for a survey strategy could also be collected through structured observation and structured interviews.
With a survey, quantative data is collected and be analyzed quantatively using descriptive statistics.Research comprises "creative and systematic work undertaken to increase the stock of knowledge, including knowledge of humans, culture and society, and the use of this stock of knowledge to devise new applications." It is used to establish or confirm facts, reaffirm the results of previous work, solve new or existing problems, support theorems, or .
