Measures of central tendency Mean, Median, Mode

Measurements of central tendency are single values that describe the typical or middle of a dataset, with the three most common being the mean, median, and mode. The mean is the sum of all values divided by the number of values, the median is the middle value in an ordered dataset, and the mode is the most frequently occurring value. The best measure to use depends on the type of data and its distribution, as outliers can significantly affect the mean.

1. Measures of Cenral Tendency of Ungrouoped Data

2. The kayak’s speed in the water is an example of quadratic e quation. The kayakers use quadratic equation to calculate the speed when going upstream and downstream a river.

3. Can you think of equations that can be transformed to quadratic equations? How will you solve equations transformable to quadratic equations?

4. Individual Practice: Transform into a quadratic equation in standard form. 1. = 2+  

5. Group Practice : To be done in groups, minimum of 2 and a maximum of 5. Find the value(s) of in the equation .  

6. Rational Algebraic Equations These are equations consisting of rational expressions. Higher Order Polynomial Equations These are equations of higher degree, especially those whose degree is greater than that of quadratic equation. Unsimplified Equations These are equations whose terms are written as product of factors and/or whose like terms are not combined or simplified.
