Research questions Flashcards
The four types of sampling design
simple random
systematic
stratified random
clustered
Simple random
randomly sample across the landscape
stratified random
pick the areas where you know the animals will be to concentrate your effort there, and then randomize within that area.
Three components of research
research question
experimental design
sampling design
Science is…
Transparent, repeatable, universal
Research question must be:
Answerable falsifiable ecological process relevant spatial extent examine comparative treatments have quantifiable response variables
Experimental Design Consists of
Experimental units treatments control replicates sample size (number of replicates) effect size power analysis
Sampling Design consists of
Sample plot sample unit sample element sample size (number of elements) variance 95% CIs.
What is the essential aspect of science?
that it is based on data
What are the three ways of counting wildlife?
census
index
sampling
What is a census?
a total count
What is indexing?
counting based on an indicator such as tracks or scat
What is sampling?
selecting representitive units from a population to measure.
use statistical design to determine variance and confidence limits
What are the four types of sampling?
simple random sampling
systematic sampling
stratified random sampling
cluster sampling
What is ecology?
the scientific study of the interactions that determine the distribution of organisms
