A researcher can access numerous qualitative data collection methods that he/she feels are relevant. In addition to the statistical methods some colleagues recommended you above, I think that a method visual representation of data can enables you t... When you average together several observations from a normal distribution, the standard deviation (SD) of your average is the SD of the individual values divided by the square root of the number of observations. The materials should also be useful if you are writing up a ‘mixed-methods’ thesis, including chapters of analysis and discussion of qualitative data. In summary, with qualitative data, the only additional measure to be concerned with to further describe that data would be the mode. There is no meaning of to take average of these two observation. Qualitative data is descriptive, referring to things that can be observed but not measured—such as colors or emotions. It is suitable for exploring attitudes and opinions regarding certain issues. Researchers often prefer to use quantitative data over qualitative data because it lends itself more easily to mathematical analysis. Reliability in qualitative studies is mostly a matter of “being thorough, careful and honest in carrying out the research” (Robson, 2002: 176). For instance, the 2018 Cost of Data Breach Study: Global Analysis gave an estimated 28 percent of probability of any type of data breach to occur in the coming two years for any organization. This type of data is collected through methods of observations, one-to-one interviews, conducting focus groups, and similar methods. and create suitable response formats. This means that the five households have an average … knowledge around a specific issue or a program, experience of … With quantitative data, the mean, variance, and standard deviation would be appropriate with symmetrical distributions while the median and range would be appropriate when the distribution is skewed … > library (MASS) # load the MASS package.
