The purpose of analyzing data is to obtain usable and useful information. The analysis, regardless of whether the data is qualitative or quantitative, may:
describe and summarize the data.
identify relationships between variables.
compare variables.
identify the difference between variables.
forecast outcomes.
Earlier, you distinguished between qualitative and quantitative research. It is highly unlikely that your research will be purely one or the other – it will probably be a mixture of the two approaches.
