Term

Definition
is the collection of data from every member of a population 


Term

Definition
is a sub collection of members from part of a population 


Term

Definition
is a measurement describing some characteristic of a population ( Sample: 2100/500trout=4.1 mean : 4.1 is parameter) 


Term

Definition
is a measurement describing some characteristic of a sample ( Sample: 45% out of 877, 45% statistic.) 


Term

Definition
Consist of number representing count of measurements ( The weight of manatees) 


Term
Qualitative Data (categorical or at attribute) Data 

Definition
can be separated into different categories that are distinguished by some non non numerical characteristic( The gender of bears) 


Term

Definition
result when the number of possible values is either a finite number or countable ( 0,1,2...) (the number of eggs a chicken lays) 


Term

Definition
result from infinitely many possible values that correspond to some continues scale that covers the range of values without gaps or interruptions . ( the gallons of milk cow gives ) 


Term

Definition
data that consists of names, labels, or categories only. Cant be arranged in low or high) ( colors, yes, no, undecided ) 


Term

Definition
can be arranged in some order, but difference between data values either cannot be determined or are meaningless(Ranks and grades) 


Term
Interval level of measurement 

Definition
like ordinal, with the difference of two values is meaningful. Data does not have a natural zero starting point.(temperature ) 


Term
Ration level of measurement 

Definition
is the interval level with addition of a natural zero starting point (weights, and ages) 


Term

Definition
we observe and measure specific characteristic but we don't attempt to modify the subject being studied. 


Term

Definition
we apply treatment and them proceed to observe its effects on the subject 


Term

Definition
data are observed, measured, and collected at one point in time 


Term

Definition
Data collected from the past by going back in time (records ) 


Term

Definition
data are collected in the future from groups sharing common factors 


Term

Definition
members from a population are selected in such a way that each individual had the same change of being selected 


Term

Definition
of size "n" subject is selected in such a way that every possible sample of the same size "n" has the same change of being selected 


Term

Definition
randomly select a starting point and the select every kth (50th ) element in the population 


Term

Definition
we simply collect result that are easy to get 


Term

Definition
we subdivide that population into at least 2 different subgroups that share that same characteristic ( age or gender)then we draw s sample from each group. 


Term

Definition
we first divide the population area into section, then randomly select some of those clusters and the choose all the members from those selected clusters.
