Currencies fluctuate, mrket behaviors change, ad trade differs, wich makes the banking industry dependant on such data in making projections about future patterns. Te meteorological department makes good use of research data in making predictions of future weather patterns. Te logic behind probability sampling is that if an individual or subject in a target population has an equal chance of being selected as a sample population, i therefore turns out that those selected thereafter give a true representation of the whole target population. A index is a composite bases its logic upon multiple nominal-level indicators.

ascale is a composite measure based on a series of continuous-level indicators. Fr instance, aresearcher may ask respondents to a) Strongly disagree; b disagree; c neutral; d agree; o e) strongly agree. Atypology is a nominal-level variable which summarizes two or more variables. Fr instance, aresearcher can create a typology of males like the man’s man; aventurous, dunkard, ad coward. Hpotheses tend to go way beyond existing measuring tools. Rsearchers must be keen when making considerations such that they identify practical strategies instruments of carrying out the experiment.

Te classical experimental design cannot be useful when dealing with casual relationships because a researcher is in total control of all variables. Te major use of this design is to isolate effects of experimental variables from its effects, epecially in external and construct validity. Coper and Schindler (2003) argued that survey research is a self-report study, wich requires the collection of quantifiable information from the sample. Acomparative analysis of its strengths and weaknesses is discussed below. Srvey research conducted online is cost Tis because a researcher has the ability to reach out to many respondents at the same time.

O the contrary, i turns out to be an expensive venture when the survey is done face to face. Wen carrying out surveys online, aresearcher tends to use little time because respondents find it convenient and thus willing to share information. O the contrary, fce to face interactions are time consuming because only a small part of the target population can be surveyed at a time. Fce to face surveys register response rates people are willing to share their information with a.. .
