Document Summary
Inappropriate measurements could affect types of data analysis: size n nature of sample also impose limitations on kinds of techniques suitable for data set. Interval/ratio variables: unit of measurement or analysis exists and thus the distances or amount of difference between the categories can be made identical across the range of categories: distances between categories are identical are identical across the. Likert scale: ordinal: many people say also ratio/interval because of the relative large number of categories. Univariant analysis: refers to the examination of one variable at a time. Diagrams: sometimes used to display quantitative data, with nominal/ordinal variables: bar/pie chart, pie shows difference in size, bar shows number of people. Interval/ratio: histogram: histogram shows relative size in each band but there is no space (difference between bar and histogram) Bivariate analysis: examines whether is a relationship between two variables, techniques depend on level of measurement of the two variables being analyzed.
