Scatterplots
| Question | Answer |
|---|---|
| two way table | a table that displays two variable data by organizing it into rows and columns |
| trend line | models the behavior of the data displayed in a scatter plot |
| linear relationship or association | when the data points lie roughly along a line |
| positive associations have this type of slope | positive |
| negative associations have this type of slope | negative |
| outlier | as part of a data set of ordered pairs it is a point that does not follow the overall pattern on a graph of the data set. |
| no association | no relationship between their data values |
| scatter plot | a graph with points plotted to show a possible relationship between two sets of data |
| Standard response to the relationship question | As the |
| negative association | is when one set of data values increases while the other decreases |
| nonlinear association | when the data seem to follow a pattern resembling anything other than a line it may be this type of association |
| strong association | when the data is close to the line, and is roughly evenly distributed on either side of the line |
| weak association | when the data is not closely associated to the line, but roughly follows the trend line |
| interpolation | an estimate of a value of a point between two given points in a data set |
| extrapolation | an estimate of the value of a point that extends beyond the data set |
| exponential form | when the answer is presented with a base and a power or a constant and a variable |
| expanded form | a number written out with each value of the digits separated by an addition sign |
| standard form | digits written in number form or as a regular number |
| scientific notation | when numbers are expressed as products multiplied to a number between 1 and 10 multiplied with appropriate power of 10 |
