|
Mean |
Quantity that has a value in between other values; an average. Way to represent the center of the data |
|
|
Error Bars |
Bars placed on graphs to show how much the data varies. Can represent standard deviation or the range of data. |
|
|
Standard Deviation |
A measure of how the spread out data points in a set are from the mean of the set. |
|
|
Relative Standard Deviation |
Measures how large the standard deviation is compared to the mean of the data set. Expressed as a percentage. |
|
|
Causation |
The idea that one thing causes something else |
|
|
Correlation |
The idea that two things vary in a patterned way. As one increases the other increases, as one decreases the other decreases. (Positive vs negative) |
|
|
Range |
The measure of the spread of a data set. It is the difference between the largest and smallest values. |
|
|
Normal Distribution |
When a large sample is taken, the most common data points are values that fall within the center of the values collected. When a frequency graph is made the graph has a bell-shaped. |
|
|
Probability |
How likely something is to happen or be true |
|
|
Null Hypothesis |
The hypothesis that there is no difference between two sets of data. |
|
|
Variability |
The description of how much the data points will be different from each other. |
|
|
Median |
The middle number in a sequence of numbers. This is a measure of center. |
|
|
Mode |
In a set of numbers the number that is most common within the set. This is a measure of center. |
|
|
Frequency |
How common a data point occurs. |
|
|
Percent Error/Change |
The percent that the experimental value differs from a known value (real value) |
|
|
Outlier |
A data point that is very different from the other data points in a set. There are statistical tests that can be done to determine if a data point is an outlier |
|
|
Significance |
In this chapter it doesn't mean that it is important but that there has been statistical tests to show that something is very likely to be true. |
