Discrete data - Has distinct values, can be counted, had unconnected points (think dots) Continuous data - Has values within a range, measured not counted, does not have gaps between data points (data is connected lines or curves). Example of discrete data - Days of the week Expressions - A group of symbols such as numbers and operators that has mathematical validity Commutative - The order in which the numbers appear in the sum can be reversed Identity property - Adding 0 to any number ...

Pie chart numerical measure: percentages best used When displaying categories as parts of the whole Bar chart (bar graph) Category counts or frequencies best used when displaying counts or frequencies for each category individually Dot Plot 5-number summary (max, Q1, median, Q3, max) Smaller data set; useful to display the distribution and show gaps and outliers (quantitative) Stem Plot (stem-and-leaf plot) 5-number summary (max, Q1, median, Q3, max) Smaller data sets; useful to disp...
