Lesson 1: Introduction to Plan Making and Implementation Flashcards
What are the 3 main components to the plan making process?
- goals and visions
- Analysis of current problems
- Creation and evaluation of alternatives
Survey
a research method that allows one to collect data on a topic that cannot be directly observed, such as opinions on downtown retailing opportunities
sampling frame
The population of interest
cross-sectional survey
A cross-sectional survey gathers information about a population at a single point in time
longitudinal surveys
Gathers information about a population over a period of time
Group-administered surveys
Respondents are gathered in a group, questionnaires are handed out to each and the questionnaires are completed within the group situation
Probability Sampling
every member of the population has an equal chance of being selected into the study
GOOD FOR QUANTITATIVE ANALYSIS
Non-probability Sampling
the members of the population will not have an equal chance of being selected, and in many cases, there will be members of the population who have no chance of being selected.
GOOD FOR QUALITATIVE ANALYSIS
stratified sampling
the population is divided into separate groups or classes, from which a sample is drawn such that the classes in the population are represented by the classes in the sample.
cluster sample
where a specific target group out of the general population is sampled from, such as the elderly, or residents of a specific neighborhood.
Nominal data
categories that do not have a natural order or ranking
Ordinal data
An ordinal scale is one where the order matters but not the difference between values.
Interval data
An interval scale is one where there is order and the difference between two values is meaningful.
Ratio data
A ratio variable, has all the properties of an interval variable, and also has a clear definition of 0.0. When the variable equals 0.0, there is none of that variable.
Quantitative variables
represent an interval or ratio measurement
qualitative variables
represent nominal and ordinal measurement
Discrete variables
are countable in a finite amount of time.
Continuous variables
can take on an infinite number of values. Example: Time
population
is the totality of some entity.
sample
a subset of the population
Descriptive Statistics
describe the characteristics of the distribution of values in a population or in a sample.
Inferential Statistics
use probability theory to determine characteristics of a population based on observations made on a sample from that population.
Distribution
is the overall shape of the observed data.
data range
difference between the highest and lowest value in a data set
Gaussian distribution
is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean. In graph form, normal distribution will appear as a bell curve
Central tendency
A measure of central tendency is a summary statistic that represents the center point or typical value of a dataset.
MEAN, MEDIAN, MODE
Mean
average of a distribution. Appropriate for interval and ratio scales
Median
middle value of a ranked distribution. Is the ONLY suitable measure of central tendency for ordinal data.
Mode
is the most frequent number in a distribution. Used for nominal data.
Variance
The average of the squared differences from the Mean. Larger variance = greater spread (flatter distribution)
Standard deviation
square root of the variance
Linear Method
uses the change in population (increase or decline) over a period of time and extrapolates this change to the future, in a linear fashion.
Exponential method
uses the RATE of growth (the % change in population over time) to estimate the current or future population.
The result is a curved line.
Modified exponential method
Modified exponential projection assumes there is a limit to the change, and at some point the growth will slow or stop. Results in an S shape curve.
Symptomatic method
uses any available data that is indirectly related to the population size (new drivers licenses).
step-down ration method
Uses the ratio between the population of a city and a county (or larger geographical unit) at a known point in time, such as the decennial census. This ratio is used to project the current or future population.
Distributed Housing Unit Method
This method uses the Census Bureau data for the number of housing units, which is then multiplied by the occupancy rate and persons per household. This method is reliable for slow growth or stable communities but is less reliable in communities that are changing more quickly.
Cohort Survival Method
Uses the current population plus natural increase and net migration to calculate a future population. The population is calculated for men and women in specific age groups.
Natural increase
the difference between the number of children born and the number of people who die during the one-time interval
Net Migration
The difference between the number of people moving in and the number of people moving out.
Economic base analysis
looks at basic and non-basic economic activities. The exporting (basic) industries make up the economic base of a region.
basic activities
Tourism (resorts)
non-basic activities
Retail stores in a tourist town
Location-Quotient (LQ
A ratio of an industry’s share of local employment divided by its share of the nation (or other level of government).
A ratio of less than 1 indicates that an area imports an industry’s products or services, a ratio of greater than 1 indicates exporting.
Shift-Share Analysis (3 components)
- National Component (share)
- Industry Component (mix)
- Regional Component (shift)
Input-output analysis
Quantitative method to assist in economic policy decision-making. The analysis links suppliers and purchasers to determine the economic output of a region. Identifies primary suppliers, intermediate suppliers, intermediate purchasers, & final purchasers.
Acquisition Cost
is the total cost that a company recognizes on its books for property or equipment after adjusting for discounts, incentives, closing costs and other necessary expenditures, but before sales taxes.
Fair Market Value
is the price that an asset would sell for on the open market.
North American Industry Classification System (NAICS)
is the standard used by Federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data about the U.S. economy.
Urbanized Area
an urban nucleus of 50,000 or more people. These urbanized areas may or may not contain any individual cities of 50,000 or more
MUST have a core with at least 1,000 people per square mile
