16
Q

What is the formula for SD?

A

o=(x-x^2)/N

17
Q

When do you use a line graph?

A

if independent variable is quantified or related to time

18
Q

When do you use a bar graph?

A

If independent variable is grouped?

19
Q

What the difference between mass and volume?

A

Mass is the amount of matter an object contains, while volume is how much space it takes up.

20
Q

Direct

A

A direct relationship is when one variable increases, so does the other

21
Q

Indirect

A

An indirect relationship is when one variable increases, the other decreases

22
Q

Constant

A

the output values are the same for all input values so the slope is zero

23
Q

Non Linear

A

the graph is not a straight line

24
Q

Peak

A

a “bump” or high point in a graph.

25
Q

What is the difference between interpolation and Extrapolation?

A

To interpolate means to make guesses about the graph in between the data points that WE HAVE COLLECTED. To extrapolate, means to makes guesses about the graph BEFORE AND AFTER the data points we have collected.

26
Q

if we are converting to a smaller unit, what happens to the number?

A

It increases.

27
Q

if we are converting to a bigger unit, what happens to the number?
