The difference between the objective of Quantitative and Qualitative research is:
Quantitative research attempts to quantify date and generalise results from a sample to the population of interest. Whereas...
Qualitative research attempts to gain an understanding of underlying reasons and motivations.
Quantitative research usually samples is a large number of cases representing the population of interest, and the respondents are randomly selected.
Qualitative research sample is usually a small number of non-representative cases.
The collection of Quantitative research is usually structured techniques such as questionnaires, and the analysis is statistical graphs and charts.
The collection of Qualitative research is individual in depth interviews or group interviews, and the analysis is the key themes that are identified in the interviews.
The outcome of the results for quantitative data is usually considered conclusive because the information can be generalised easily to a population.
Qualitative data however, can be open for debate because it is based on the opinions and views of people and goes into much more detail.
There are three different sampling methods:
Systematic Random Sampling: numbers are generated and one person per random number is selected.
Simple Random Sampling: everyone is assigned a different number, for example ranging from 1 to 100 and every Nth number is selected.
Stratified Random Sampling: a certain group of people are selected to question, based on the actual demographic you are aiming for.
To collect data for our audience research we will use Simple Random Sampling, because it's the simplest and seeing as we have a list of all the possible respondents, it's the easiest to select them in this way.
