| The normal approximation for data |
|
Definition
| estimates percentage of entries in an interval |
|
|
Term
|
Definition
| the percentile is a location. It implies percentage above or below |
|

Term
| Change of Scale: adding the same number to every entry does what |
|
Definition
| it adds that constant to the average and the SD does not change |
|
|
Term
| Change of Scale: multiplying every entry ona list by the same positive number does what |
|
Definition
| it multiplies the average and teh SD by that constant |
|
|
Term
| Do changes of scale change the standard units? |

|
|
Term
| Standard Units tell us what |
|
Definition
| how many SD's a value is above or below the average |
|
|
Term
| Do many histograms have roughly the same shape as the normal curve |
|
Definition
|
|
Term
| If a list of numbers follows the normal curve, the percentage of entries falling in a given interval can be estimated by converting the interval to standard units, and then finding the corresponding area under the normal curve. This procudure is called wh |

Term
| are the average and the SD good summary statistics? |
|
Definition
| Yes. A histogram can be reconstructed fairly well using the SD and the average |
|
|
Term
