Using the fx-83/85GT CW for statistics
Lesson details
Learning outcome
I can use the fx-83/85GT CW to perform calculations with data.
Key learning points
- Some calculators can perform more than just basic calculations.
- The fx-83/85GT CW can produce a statistical summary of a set of data.
- The summary includes the mean, median, upper and lower quartiles.
Keywords
Frequency - The frequency is the number of times an event occurs; or the number of individuals (people, animals etc.) with some specific property.
Mean - The (arithmetic) mean for a set of numerical data is the sum of the values divided by the number of values. It is a measure of central tendency representing the average of the values.
Median - The median is the central (middle) piece of data when the data are in numerical order. It is a measure of central tendency representing the average of the values.
Mode - The mode is the most frequent value. It is a measure of central tendency representing the average of the values.
Statistical summary - A statistical summary sums up the features of a data set. It may contain the mean, median and/or mode which measure the central tendency. It may also contain the range which measures the spread.
Common misconception
Calculators can only be used to add, subtract, multiply or divide.
They can be used to perform basic calculations but they can also do so much more.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
