Document Summary
Conceptual variables are the ideas that form the basis of a research hypothesis i. e. self- esteem, parenting style, depression and cognitive development. Measurement involves turning conceptual variables into measured variables, which consists of numbers that represent the conceptual variables frequently referred to as measures of the conceptual variables. Basic assumption involved in testing research hypotheses: if the research hypotheses is correct and if the measured variables are adequate then a relationship between the two measured variables will be observed. When interval scales have a true zero point they are known as ratio scales. Measures in the behavioural science normally constitute only ordinal scales whose numbers indicate whether there is more or less of the conceptual variable, but they do not indicate the exact interval between the individuals on the conceptual variable. Individuals are asked to respond to questions posed by an interviewer or a questionnaire.
