Using statistical models worksheet

A model is an equation fitted to real data. Put an x in to predict a y. To find which x gives a certain y, set the model equal to that y and solve: a quadratic model can give two answers, and both may make sense. The starting value of an exponential model, its y-intercept, is the amount at the start of the time count.

How to do these

A model is $y = 0.25 x^{2} - 10 x + 200$ . For which $x$ is $y = 136$ ?

Set the model equal to 136: 0.25x^2 - 10x + 64 = 0.
Use the quadratic formula: x = (10 ± sqrt(100 - 64)) / 0.5.
That is (10 ± 6) / 0.5, so x = 8 or x = 32.

The answer is $x = 8$ and $x = 32$ .

Where students go wrong

Keeping only one answer. When a quadratic model is set equal to a value it usually crosses it twice, once going down and once coming back up, and both x-values answer the question unless the context rules one out.

Also called quadratic regression, exponential regression, interpreting models, using a model to predict or line of best fit and r squared.

What you can put on this worksheet

Quadratic models: evaluate, and solve for x: A model for a car's gas mileage, in miles per gallon, is $y = - 0.02 x^{2} + 2.24 x - 33.72$ , where $x$ is its speed in miles per hour. Find $y$ when $x = 59$ , to the nearest tenth. → $28.8$
What the y-intercept means: If $y$ is the value of a house, in thousands of dollars, $x$ years after 1900, a model is $y = 58.4 {(1.04)}^{x}$ . What does the $y$ -intercept mean? → In 1900 the house was worth about 58.4 thousand dollars.
The line and r squared: Find the line of best fit and $r^{2}$ , each to the nearest hundredth.
$\begin{array}{ccccccc} x & 3 & 5 & 7 & 9 & 11 & 13 \\ y & 15 & 24 & 22 & 29 & 29 & 35 \end{array}$ → $y = 1.74 x + 11.72$ , $r^{2} = 0.89$

That is the closest comparison, and Kuta Software is good software. It is also paid software you install on a computer. These worksheets run in a browser tab for free, with no account and nothing to install. Like Kuta, the using statistical models questions are generated when you ask for them rather than pulled from a fixed set of files, so two classes never get the same sheet, and the answer key comes with it.

Yes. There are three levels, and you can tick more than one for a sheet that mixes them, in which case the questions come out easiest first. The harder levels are not just larger numbers: they ask for something the easy ones do not.
