an input and gives as an output. You can sometimes Tnd an inverse function by reversing the processes that deTne the Trst function in order to deTne the second function.
maximum
A value of a function that is greater than or equal to all the other values, corresponding to the highest point on the graph of the function.
minimum
A value of a function that is less than or equal to all the other values, corresponding to the lowest point on the graph of the function.
model
A mathematical or statistical representation of a problem from science, technology, engineering, work, or everyday life, used to solve problems and make decisions.
negative relationship
A relationship between two numerical variables is negative if an increase in the data for one variable tends to be paired with a decrease in the data for the other variable.
non-statistical question
A non-statistical question is a question which can be answered by a speciTc measurement or procedure where no variability is anticipated, for example:
• How high is that building?
• If I run at 2 meters per second, how long will it take me to run 100 meters?
numerical data
Numerical data, also called measurement or quantitative data, are data where the values are numbers, measurements, or quantities. For example, the weights of 10 diWerent dogs are numerical data.
outlier
A data value that is unusual in that it diWers quite a bit from the other values in the data set.
