INEQUALITIES Definition An inequality is a mathematical sentence that uses symbols such as <, ≤,>, or ≥ to compare two quantities. Our aim is to have x (or whatever the variable is) on its own on the left of the inequality sign:   That inequality is “solved”. Example 1: Example 2: Note: Change sign when… Continue reading Inequalities

This is the Part 2 of my previous post Measures of Central Tendency(Part 1) Median Median is the middle values. Example: Find the median. So the median is 9.   If the total number of numbers (n) is an odd number, then the formula is given below: Example: Find the median. So the median is 5.… Continue reading Measures of Central Tendency(Part 2)

Measures of Central Tendency is a single value that attempts to describe a set of data by identifying the central position within that set of data. The mean, median and mode are all valid measures central tendency, but under different conditions, some measures of central tendency become more appropriate to use than others.   Mean… Continue reading Measures of Central Tendency(Part 1)
