The levels of measurement from the lowest to the highest level are nominal‚ ordinal‚ interval‚ and ratio Variables measured at the nominal level of measurement are at the lowest level and must follow three rules: (1) the data categories must be exhaustive (each datum will fit into at least one category identified by the researcher)‚ (2) the data categories must be exclusive (each datum will fit into only one category)‚ and (3) the data cannot be rank ordered. Nominal data differ from ordinal data

Practice Assignment The goal of this assignment is to provide a “bridge” between the first two weeks of lectures and assignment 1 for those either new to R or struggling with how to approach the assignment. This guided example‚ will not provide a solution for programming assignment 1. However‚ it will guide you through some core concepts and give you some practical experience to hopefully make assignment 1 seems less daunting.

1.2 - Below we list several variables. Which of these variables are quantitative and which are qualitative? Quantitative means that the measurement of the value gives an actual quantity that can mean “how much”‚ or “how many”. Whereas qualitative means we are simply recording into which of the categories the element falls. (Bowerman‚ O’Connell‚ Murphree‚ Orris‚ J. B. (2012). Essentials of Business Statistics 4th ed.). A.
