Recommended: Strength and weakness of the qualitative method
Penton Media sample plan was created from the use of a stratified disproportionate random sampling with subscribers that are considered as belonging to one of 42 cells (seven industry groups by six job titles). Penton received a total of 710 complete questionnaires. Penton discovered that 676 out of the 710 respondents were responsible for making decision at their companies. However, Penton examined only the responses for the 676 buyers. Penton analyzed the 676 respondents by weighing responses in each cell divided by the percentage of the total population. An extensive follow-up was by telephone to 40 respondents in hopes of getting an intense understanding of behavior and attitudes. The researchers started the search by a pretest of reader-targeted mail questionnaire by phone with small sample drawn from its database of 1.7 million domestic subscribers. Penton conducted a second pre-test, which gave the researchers the opportunities to refine questions based on the information they obtained from the pretest. Penton completed the surveys by mailing to 4,000 managers, executive, engineers, and purchasing agents that Penton selected form a database.
Strengths
Penton Media sampling plan had several strengths such as the use of the telephone inquiries that allowed Penton to reach respondents that otherwise might not be available in person. Penton Media using the stratified random sampling was positive because it minimizes cost. The stratified random sampling also minimized variability. The stratified random sampling gets a more precise estimate of the population. The stratified sampling can accommodate the structure of the population. Penton Media improved population representatives in the study. Penton sampling plan has a high statistical precision. Penton response rate was high enough to create statistically valid inferences. The margin of error for the survey was + 4 percent at the 95 percent level of assurance. Penton sampling plan improves the possible for the units to be more equally distributed over the population. Penton media sample plan saved time.
Weaknesses
The weakness of Penton sampling plan is that there is a large variance among the subgroups. The stratified disproportionate random sampling is complex compared to simple random. The different methods that Penton used to get their respondents could be challenging.
Research design
Research design methods consist of qualitative, quantitative and mixed methods, as well as many other methods.
Two sampling methods include mail surveys and convenience sampling, a variation of a nonprobability sample. Mail surveys, inexpensive way to contact individuals over a large geographical area, provide anonymity to the respondent, and eliminate interview bias. Convenience sampling, a nonprobability sample, the only criteria is the convenience of the unit to the researcher, fast and uncomplicated, but the sampling error not determined.
There are two types of research that can be conducted in research studies, these are qualitative and quantitative (Newman, 2011). Qualitative research is a process that uses detailed oriented methodology that tries to achieve a profound knowledge or understanding of specific incident and circumstance, wh...
If research and theory are inextricably linked, then one cannot understand the nature of theory without first understanding the nature of research. There are two types of research design in the scientific inquiry - qualitative and quantitative. Qualitative and quantitative research designs are the basis of the scholarly study utilized regarding the purpose of the research and recourses available for investigation. There are situations when researchers apply both types of design, as in cases when it is important to enhance internal and external validity, credibility, and reliability of the results. Both qualitative and quantitative designs have advantages and disadvantages that can either benefit the study or jeopardize the research

Confidence concerning the size of the population submitted to the questionnaire had provided enough margins to ensure the minimal distortion and pollution of the data by the odd responses possibly contaminating the overall outcome. With a range of double to five times the demanded sample by the author the instrument and the results could be observed with a substantial marge of safety and be coerced with strong validity.
It is selected directly and intentionally individuals in the sample, depending on the ease of access. It helps in gathering useful information and data that are impossible by using probability sampling technique, which needs formal access to list of population (Goertz and Mahoney, 2012). This sampling is easy and efficient but not one of the favourites because in these studies the key is to extract the maximum amount of information few cases of the sample, and the method for convenience cannot supply the richest sources of information. It is an easy and economical process which allows move on to other methods as the data are collected (Goertz and Mahoney, 2012). As in quantitative research, it is to select cases that are available or convenience to the researcher. It is highly recommended because it reflects that the researcher has not given much thought to the strategy to choose subjects or observation units. Moreover, it is almost always possible to devise some criteria
Qualitative and Quantitative study designs both can be beneficial in research design. They both provide valuable options for researchers in the field. These techniques can either be used separately in a research study or they can be combined to achieve maximum information. This paper will define the terms qualitative and quantitative; describe the similarities and differences between each; discuss how qualitative and/or quantitative research designs or techniques could be used in the evaluation of my proposed research; and discuss why linking analysis to study design is important.
...ll be preferred since it will involve dividing of the population into homogenous subgroups then taking a sample in each subgroups this procedure will also be preferred because it will ensure that certain sub groups in the population are represented in the sample in proportion to their number in the population (Kombo and Tromp, 2006) the procedure will also be preferred since all the target population had an equal chance of being selected and inclusion of small groups which otherwise could have been omitted entirely by other sampling methods (Kothari, 2004) hence the researcher will use this sampling procedure to ensure both management levels are included in the study since the procedure classified the population first into homogenous groups and give each target population equal chance to be picked. The sample size to be picked will be 79% of the target population.
Creswell (2009), states that there are three types of designs, qualitative, quantitative and mixed methods. Smith and Davis (2010) states that qualitative research is a field of enquiry that is conducted in a natural setting by a researcher, who may be involved in, or may be part of the data collection process; as it utilizes the views of informants as the basis for the report. Qualitative research attempts to gain and in-depth, holistic picture of the phenomenon one wishes to study by interacting closely with the people being studied; the data collected are usually in the form of words or pictures.
Lack of response is the main disadvantage for mail surveys. The group survey is another low cost form, however the individual respondent is interviewed in a group. The disadvantage with group surveys are the logistics of marshaling the respondents to one location and the perception by respondents that grouping posses less anonymity. Electronic surveys are a relatively new addition in survey research and could very well become comparable to the telephone survey. Electronic surveys are advantageous for the low cost as well as ease in delivery. Because the delivery method is through internet, and the general population does not
Every research study should describe the methods used for collecting, analysing and interpreting data. Research methodology is a systematic solving of the research problem and includes all the tools and methods used in the research process.
This paper discusses different types of sampling techniques used in quantitative research. It begins by looking at probability sampling (also known as random sampling) before discussing non-probability sampling (non-random sampling). The discussion ends by looking considerations that should be made before selecting a sampling technique before concluding. Because quantitative researchers prefer probability sampling and only use non-probability on rare occasions the e...
The nature of research instruments, the sampling plan and the type of data the research design constitutes the blueprint for the collection, the measurement and analysis of data. It aids the researcher in the allocation of his limited resources by posing crucial choices.
According to Mouton, research designs are tailored to address different kinds of research questions. Thus, when attempts are made to classify different kinds of research studies to different design types, they are classified by the kind of research questions they are able to answer. Research designs can be mapped out to the types of research questions (research problem) using four dimensions: 1) empirical versus non-empirical dimension, 2) using primary versus using secondary data, 3) the nature of the data (numerical versus textual data) and 4) the degree of control (structured (laboratory) conditions versus natural field settings)
The Importance and Appropriateness of Utilizing Different Methodologies for Research. Introduction The process of research entails the logical as well as systematic search for useful data and information with regard to a specific topic (Jha, 2008). It is also comprised of the investigation of the best, most cost effective and appropriate solutions to both social and scientific issues, following an objective and logical analysis. Jha, (2008) defines research as the search for knowledge and the discovery of the truth. During this process, the data can be gathered from a wide pool of sources among them interviews, books, nature among others.The data can then be analyzed with the appropriate data analysis tools, so as to report the findings
