Document Summary
Representation of a frequency distribution of a qualitative variable by way of rectangles whose heights are proportional to relative frequencies places over each category. A bar chart such that the categories have been sorted according to frequency (in descending order) The frequency distribution represented by a circle that is divided into categories c1, C2, etc. where the size of each partition is proportional to the relative frequency. A network diagram used to find and analyze the various outcomes in a multi-stage sampling. Representation of a frequency distribution by ways of rectangles whose width represents the class width and whose heights are proportional to relative frequencies. A line graph method of displaying data by grouping the data into quartiles. Recall, there are five quartiles, the min, max, median, q1, and q3 where a box is drawn around the iqr. A data value such that 50% of the information lies to the left and the other half lies to the right.
