We now take for granted the periodic table , yet it took descriptive research to devise it. Descriptive research generally precedes explanatory research. Hence, descriptive research cannot describe what caused a situation. Thus, descriptive research cannot be used as the basis of a causal relationship , where one variable affects another. In other words, descriptive research can be said to have a low requirement for internal validity. The description is used for frequencies , averages and other statistical calculations.
Often the best approach, prior to writing descriptive research, is to conduct a survey investigation. Qualitative research often has the aim of description and researchers may follow-up with examinations of why the observations exist and what the implications of the findings are. In addition, the conceptualizing of descriptive research categorization or taxonomy precedes the hypotheses of explanatory research.
Descriptive research is also known as Statistical Research. The main goal of this type of research is to describe the data and characteristics about what is being studied. The idea behind this type of research is to study frequencies, averages, and other statistical calculations. Although this research is highly accurate, it does not gather the causes behind a situation. Cross-sectional Surveys — The data is collected at one point in time from a sample that represents a larger target population Longitudinal Surveys — Used to study data that may change over time.
The three main types of listed below: Trend — Surveying a sample population at different points in time. Cohort — Surveying the same target population repeatedly, but the samples within the population being studied may be different. Panel — Collection of data at various time points with the same sample respondents. Survey Administration — How the survey will be administered depends on whether the survey is a questionnaire or an interview.
Common methods of administering surveys include: Some of the factors that need to be considered in making this decision include the characteristics of the sample population, the types of questions, the anticipated response rate, cost and time. Modes of Survey Delivery Writing Good Survey Questions - Writing good survey questions is a critical part of the survey process because the quality of the questions and the structure of survey will impact the reliability and validity of the data.
The following links provide great tips for writing good questions. Writing Survey Questions Sampling and Choosing Participants — Researchers must spend time considering the target population, how to sample it, the appropriate sample size, and how to reduce bias. These topics are covered in the resources below.
Sampling — Who to Survey Survey Response Rate - The response rate of a survey is very important to the credibility of the research results. The following links discuss how to determine an appropriate response rate to a survey and how to increase responses. Survey Response Rates Once the survey has been designed and delivered, the data that is collected will need to be analyzed.
