Examples of Quantitative Variables
The further I get away from 0 for the skewedness the further I deviate from normal distribution. Non Skewedness is close to zero or away from 0. Statistics of zero indicates no skewedness at all.Mean is the most commonly used measure of central tendency and not very often will you use median. This is also because it is the best known measure that most people call “average” and normally used to described tendency in interval-ratio variables ( Frankfort-Nachmias, & Leon-Guerrero, 2015). The creation of pie chart was one of the best, yet olden discovery in the most popular way to visualize data. Although, graphs can give us a very immediate sense as to whether any relationship exists between two variables (Frankfort-Nachmias, & Leon-Guerrero, 2015). plot that lets you discover, and show, the underlying frequency distribution (shape) of a set of continuous data. Histogram can use an interval-ratio variable in calculating interval between values that may not be interpretable in ordinary measure.
