Evaluating the Limitations of Market Research

The population sampled due to its specific nature i.e., college students, and college graduates would need to be contemplated in regards to the testing results as it is offered as a depiction of the general population.

this study is the use of convenience sampling, as previously mentioned. Black et al. (2000) make

The researchers used purposive sample but did not give any explanation as to why this choice sampling was made. It is essential to describe the sampling process in a research where this facilitates the reader to distinguish any bias in the whole sampling process. In studies using participants, the process of how to select, access, inform and retain research participants requires considerable thought. Sampling is a key issue, because it is

Marketing research is very important component of a business used to identify and define the opportunities and problems that they will encounter on the market. The aim

Describe the experimental method, state its advantages and disadvantages, and distinguish between independent and dependent variables.

In order to maintain consistency throughout the study, each of the six subjects will utilise the same source for data collection. Due to the fact that sites vary in precision (number of decimal places), activity format and number of trials, this particular measure will assist in ensuring that the evidence used to address the claim is both accurate and reliable.

Secondary information is data which is derived from primary information and can be found via books, newspapers, internet etc. Secondary information is less reliable than Primary information because you cannot be certain as to how precise it is.

The unit of analysis was the individual mobile phone service subscriber. Data were analyzed in two major stages, that is, through descriptive statistics and specific tests of hypothesis. Cross tabulation was used to analyze demographic variability of the respondents. Descriptive statistics including measures of central tendencies, measures of dispersion, frequencies and percentages were calculated to examine the respondents’ characteristics. These statistics showed the basic characteristics of research variables. The second stage of analysis focused on testing specific hypotheses of this study. To analyze qualitative data, content analysis was used following the suggestion by SPSS BOSS (2015). As noted by

Probability sampling, also known as random sampling, requires that every member of the study population have an equal opportunity to be chosen as a study subject. For each member of the population to have an equal opportunity to be chosen, the sampling method must select members randomly. Probability sampling allows every facet of the study population to be represented without researcher bias. Four common sampling designs have been developed for selection of a random sample: simple random sampling, stratified random sampling, cluster sampling, and systematic sampling (Burns & Grove,

Based upon information provided this study was appropriate conducted as a purposeful sampling but, this study

M1: Explain, with examples, how different market research methods are appropriate to assist different marketing situations. Looking back at the market research methods that could be used to collect information, methods such as questionnaires/ survey, observation, focus groups, experimentation, internet, website monitoring etc. I am going to select 3 primary and 3 secondary methods of research from the ones I have written about. I have chosen 3 primary researches which are: •

An example of population can be a bowl containing 500 balls of which or it can be 8,000,000 patients. The method of random selection remains same for both kinds of populations. However, the sample size can differ. While doing random sample the large population can be contracted into subsets such as categorizing patients by the name of their hospitals, making a list of those hospitals, assigning numbers in sequence to each of them, figuring out the sample size. A random number generator can also be used to decide the sample size, for e.g. 50 out of 500.

Finally, Vodafone also segment their market by usage rates of their customers. Vodafone offer a variety of calling plans to suit customer's usage rates. They even offer specialist calling plans which are tailored to suit businesses. Through this method of segmentation Vodafone are able to identify their most valuable customers.
