and data must be gathered to make sure that all details match and that all requirements are met. It would be safe to assume that our theory that the larger the house and the more rooms a house has‚ the more expensive the price of the house will be. The three major variables in our data summary are: number of bedrooms‚ size of the house‚ and number of baths. According to our information compiled (see attached excel file for mega stat)‚ the measure of tendency that best represents the data set

Using qualitative data collection method‚ it rely on random sampling and structured data collection instruments that fit diverse experiences into predetermined response categories. They produce results that are easy to summarize‚ compare‚ and generalize. Quantitative research is concerned with testing hypotheses derived from theory and/or being able to estimate the size of a phenomenon of interest. Depending on the research question‚ participants
