SSCI 2910U Lecture Notes - Lecture 2: Bar Chart, Upper Class, Dependent And Independent Variables
Document Summary
Slide 3: variables are very important in da, everything must be turned into a variable to analyze it. Variable is a trait/characteristic that can change volume from case to case (ex. 2 year old boy, 16 year old girl) A variable is anything that can assume different values (ex. Of a non-variable is a person"s name, it does not change, gender or ethnicity) Quantitative variable can be measured numerically, numeric values (ex. Discrete variable can assume finite or count the number of values, we can"t have 2. 5 members in a household rather 2 or 3 beginning from 0. we don"t deal with points, we want whole numbers. Continuous variables can assume in finite and can be obtained in values, can be measured in a continuous way, measured in a smallest unit. Dependent variable is something we are trying to explain, the factors we use to explain the dependent variable (effect) is known as the independent variable (cause).
