Prob And Stats 1.1-1.3

Front 1

data

Back 1

observations (such as measurements, genders, survey responses) that have been collected

Front 2

statistics

Back 2

a collection of methods for planning experiements obtaining data and then organizing , summarizing, presenting analyzing, interpretying and drawing conclusions based on the data

Front 3

population

Back 3

is the complete collection of all elements (scores people, measurements and so on) to be studied. The collection is complete in the sense that it incluseds all subjects to be studied

Front 4

census

Back 4

is the collection of data from every member of the population

Front 5

sample

Back 5

a subcollection of members selected from a population

Front 6

parameter

Back 6

a numerical measurement describing some characteristics of a population

Front 7

statistic

Back 7

a numerical measurement describing some characteristic of a sample

Front 8

Quantitative data

Back 8

consists of numbers representing counts or measurements

Front 9

Qualitative Data

Back 9

can be seperated into different categories that are distinguished by some nonumerical characteristic

Front 10

discrete data

Back 10

result when the # of possible values is either a finite number or "countable"

Front 11

continuous data

Back 11

result from infinitely many possible values that correspond to some continuous scale that covers a range of values w/out gaps, interruptions or jumps

Front 12

Nominal LOM

Back 12

characterized by data that consist of names, labels, or categories only. Can't be arranged in an ordering scheme (low to high, etc)

Front 13

Ordinal LOM

Back 13

data at this level of measurement can be arranged in some order, but differences between data values can't be determined or are meaningless

Front 14

Interval LOM

Back 14

like the ordinal level, with the additional property that the difference between any two data values is meaningful. However, data at this level do not have a natural zero starting point (where none of the quanity is present)

Front 15

Ratio LOM

Back 15

the interval level w/ the additional property that there is also a natural zero starting point (where zero indicates that none of the quanity is present) For values at this level, differences and ratios are both meaningful
