principles of the scientific method - -empirically testable, replicable, objective, transparent, falsifiable, logically consistent -Qualitative Research - -research focuses on collecting, analyzing, and interpreting non-numerical data. Naturalistic and interpretative -Quantitative - -research focuses on gathering numerical data and generalizing it across groups of people or to explain a particular phenomenon -an observational study - -we measure or survey members of a sample without trying to affect them -experimental study - -conditions are controlled and manipulated by the experimenter in order to study the effects. -qualitative/ categorical - -nominal and ordinal -quantitative/numerical - -interval/ratio -nominal - -Unordered - the categories have no distinct or logical order. The categories are mutually exclusive can be binary or multinomial -ordinal - -Ordered - there is a clear ordering of the categories. The categories differ in order, but the distances between the categories is not known -numerical values - -interval or ratio -interval - -Numerical values without a true zero point. 0 does not indicate a complete lack of the quantity being measured. Degrees Celsius is an example. -ratio - -Numerical values with a true zero point.Ratio variables don't have a negative number like an interval variable.Ratio variables allow for addition, substraction, multiplication, and les: weight, length, frequency of words in a text Numerical values with a true zero point.Ratio variables don't have a negative number like an interval variable.Ratio variables allow for addition, substraction, multiplication, and les: weight, length, frequency of words in a text
