Mean, Median, Mode, Range and Outlier in a PowerPoint Presentation
This slideshow lesson is very animated with a flow-through technique. It was made for my Algebra 1 class, but can be used for lower grades aw well. The lesson teaches how to solve for mean, median, mode and range. It also teaches to identify outliers in a set of data and find the measure of central tendency.
The presentation has 59 slides with lots of whiteboard practice. Use as many or as few of the problems to help your students learn each concept. For more PowerPoint lessons & materials visit:
Students often get lost in multi-step math problems. This PowerPoint lesson is unique because it uses a flow-through technique that helps to eliminate confusion and guide the student through the problem. 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. Every step of every problem is shown, even the minor or seemingly insignificant steps. A helpful color-coding technique engages the students and guides them through the problem. Twice as many examples are provided, compared to a standard textbook. All lessons have a real-world example to aid the students in visualizing a practical application of the concept.
This lesson applies to the Common Core Standard:
Expressions and Equations 7.SP
Draw informal comparative inferences about two populations.
4. Use measures of center and measures of variability for numerical
data from random samples to draw informal comparative inferences
about two populations. For example, decide whether the words in a
chapter of a seventh-grade science book are generally longer than the
words in a chapter of a fourth-grade science book.
Summarize numerical data sets in relation to thier context, such as by: 5. 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 devations from the overall pattern with reference to the context in which the data were gathered.
Please note that the PowerPoint is not editable.
If you need an alternative version because your country uses different measurements, units, slight wording adjustment for language differences, or a slide reordering just ask.
