Nominal Measurement
{"Image DocumentName": "Nominal Measurement", "Image ImageDescription": "This is the simplest and lowest level of measurement. It is useful for categorizing variables into sub-classes by assigning a numerals of any other symbols to mutually exclusive sub-classes. For example the variable of sex is classified as males \u20181\u2019 and females \u20182\u2019 or as \u2018M\u2019 and \u2018F\u2019. Nominally scaled numbers only act as a labels for the classification. Therefore, we cannot perform any arithmetic operations on these numbers because they only indicate the presence or absence of some characteristics.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
