Lesson details
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.
