This PowerPoint Presentation was made for my Pre-Algebra class, but can easily be adapted for lower grades. The lesson teaches students how to solve for mean, median, mode and range along with how to identify outliers within a set of data (as well as their effects on a data set). Through analytical thinking, students can decipher how to find the measure of central tendency (which average best describes the data set).
This presentation has 50 slides with lots of examples and practice problems. This presentation is unique because it helps to eliminate confusion as it guides students through the problem in order to calculate the solution. The lesson highlights each step of the problem as the teacher is discussing it, and then animates it to the next step within the lesson. A helpful color-coding technique engages the students and guides them through the problem. Real-world examples are used to aid students in visualizing a practical application of the concept.
This Presentation is lesson applies to the following Common Core State Standards:
6.SP.3 - Recognize that a measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number.
6.SP.5 - Summarize numerical data sets in relation to their context, such as by: Giving quantitative measures of center (median and / or mean) and variability (interquartile range and / or mean absolute deviation), as well as describing any overall pattern and any striking deviations from the overall pattern with reference to the context in which the data were gathered.
7.SP.4 - Draw informal comparative inferences about two populations. Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations.
