Statistics Types of Data Types of Variables Scales of measurements

Types of Data Variable and Constant Quantitative and Qualitative << Home

Variable and Constant �Variable - a symbol used to represent a quantity - used to distinguish between 2 types of quantities being considered, separating them into those available at the start of a process and those being created by it, where the latter (dependent variables) are dependent on the former (independent variables). Constant - something that never changes, as opposed to a variable. << Home

Quantitative and Qualitative �Qualitative Data Overview: Deals with descriptions. Data can be observed but not measured. Colors, textures, smells, tastes, appearance, beauty, etc. Qualitative → Quality

�Quantitative Data Overview: Deals with numbers. Data which can be measured. Length, height, area, volume, weight, speed, time, temperature, humidity, sound levels, cost, members, ages, etc. Quantitative → Quantity << Home Examples >>

Types of variables Discreet and Continuous Dependent Variables and Independent Variables << Home

Dependent and Independent Variables �Dependent Variables: value depends on the value of the independent. �Independent Variables: typically the variables representing the value being manipulated or changed and the dependent variable is the observed result of the independent variable being manipulated. << Home

Discreet and Continuous * Discreet - if there are only a finite number of values possible or if there is a space on the number line each 2 possible values. • Continuous - makes up the rest of the numerical data that is usually associated with some sort of physical measurement. << Home
