3 Parts of the Plan Making Process
1) Goals & Visions
2) Analysis of Current Problems
3) Creation & Evaluation of Alternatives
Survey
A research method that allows one to collect data on a topic that cannot be directly observed - like opinions
Population of interest for a survey
Sampling Frame
Cross Sectional Survey
Gathers info about a population at a single point in time - how do you feel about the park as of today?
Longitudinal Survey
Conducted over a period of time - like satisfaction surveys conducted every few years
Written Surveys
Group Administered Surveys
Drop-off Survey
Oral Survey

Online Survey
Survey Design Points
Make all questions clear (don’t use technical jargon).
Make sure each question only asks about one issue.
Make questions as short as possible.
Avoid negative items as they can confuse respondents.
Avoid biased items and terms.
Use a consistent response method, such as a scale of 1 to 7 or yes/no.
Sequence questions from general to specific.
Make the questions as easy to answer as possible.
Define any unique or unusual terms. For example, when you are conducting a survey about open space zoning be sure to define what the term means.
Sample Design
Sample should represent the population where info is being gathered.
Probability Sampling
There is a direct math relation between sample and population - precise conclusions can be drawn
Non-probability sampling
a sampling technique where the odds of any member being selected for a sample cannot be calculated.
Examples of Probability Sampling
Random
Systematic
Stratified
Cluster
Examples of non-probability sampling
Convenience
Snowball
Volunteer
Volunteered Geographic Information
Sampling where special group are targeted
Systematic, Stratified, Cluster
Stratified Sampling
Pop is divided into groups/classes, and a proportional sample is drawn from each class
Cluster Sampling
a form of stratified sampling where a specific target group out of the general pop is chosen
Convenience sample
readily available individuals are chosen
Snowball sample
One participant suggests other participants
Volunteer sample
Self selected respondents
Volunteered Geographic Information
Volunteer sample where participants enter info on a web map
