Question
Answer
What is nominal?   show
🗑
show order, but no magnitude. A,B,C,D but has no significant value. has values that are ranked so that inferences can be made regarding the magnitude. However, ordinal data has no fixed interval between values.  
🗑
WHat is Interval?   show
🗑
show has an ordered relationship and equal intervals. Distance is an example of ratio data because 3.2 miles is twice as long as 1.6 miles.  
🗑
show Average  
🗑
What is a median?   show
🗑
WHat is a mode?   show
🗑
What is a range?   show
🗑
What is a stepdown method?   show
🗑
What is a cohurt method?   show
🗑
What is a sympothomatic method?   show
🗑
show The area is exporting jobs.  
🗑
While in some cases we want to know the central tendency of a dataset, in other cases we want to know the extent to which data differs from each other.   show
🗑
is the average squared difference of scores from the mean score of a distribution.   show
🗑
show Standard Deviation  
🗑
is the standard deviation of a sampling distribution.   show
🗑
gives an estimated range of values which is likely to include an unknown population parameter.   show
🗑
show Chi Square, Chi Square is commonly used for probability distributions in inferential statistics. This Chi Square distribution is used to test the goodness of fit of an observed distribution to a theoretical one.  
🗑
show Cohurt Survival method  
🗑
is the difference between the number of children born and the number of people who die during one time interval. Migration and Natural increase are basically part of the Cohort-Survival method.   show
🗑
show Satisficing  
🗑
technique allocates a portion of the projected expansion to sub-regions or population centers based on the center's present share of the employment.   show
🗑
show Regression Analysis  
🗑
What is a normal distribution?   show
🗑
A variable where the value is fixed or static.   show
🗑
The assignment of numbers of symbols for the purpose of designating subclasses that represent unique characteristics.   show
🗑
is the assignment of numbers or symbols for the purpose of identifying ordered relationships of a particular characteristics without specified intervals.   show
🗑
characteristics with the ability to determine differences in amounts.   show
🗑
ordered relations of some characteristic with the ability to determine differences and an absolute zero point.   show
🗑
In population projections this type of method compares the study area (city) to a larger study area (state).   show
🗑
show Use a heterogeneous population  
🗑
What can be described as a measure of dispersion around the mean that is calculated as the average of the sum of the squared deviations from the mean?   show
🗑
very low speeds, frequent stoppages, volume is greater than capacity   show
🗑
show represents the mean, mode, and median.  
🗑
show To provide a statistically significant sample

🗑
show strategies for projecting populations.  
🗑
show Descriptive  
🗑
graphic skew to the right means?   show
🗑
