Document Summary
Collect data- observation: how to take measurements. Data can be observed and put into categories but not measured. Beytween 2 values there is an infinite number of other values. Same principle of typology but with different types. Only tells us order of categories, not about the difference between them. Can do + and but not x and / Fixed and equal units between points on the scale. Ratio between units of measurements remains the same. Can do -, +, x, and / Can have infinite amount of values but depends on measurement. An accurate measurement will have a smaller error. Can be increased by having instruments with smaller increments. Precision: concerns range or results obtained if measurement is repeated. 7 and 9 in between = 8+- 1: analyzing and presenting data. Measures intended to provide a summary of. Proportion: what part of whole is composed of something. Proportions always reange between 0 and 1. 0.
