BIOL 2600 FINAL EXAM QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS VERIFIED
What is a hypothesis?
A hypothesis is a proposed explanation for a phenomenon that is expressed as a testable question.
What are features make a hypothesis good?
1) Be testable
2) Be falsifiable
3) Be parsimonious
4) Have a defined scope
What is explanatory data analysis?
Uses the data themselves to decide how to conduct the statistical analysis. Built on simple visualizations
of the data.
What is Fisher's hypothesis testing paradigm?
The purpose of data collection is to facilitate the testing of a hypothesis
What is Tukey's hypothesis testing paradigm?
Built on Fisher's hypothesis testing and focuses on the hypothesis being developed from exploratory
data analysis.
What is data dimensionality?
, A dimension of mathematical space is the minimum number of coordinates needed to specify any point
within it. A point on a line requires 1 dimension, a point on a plane requires 2 dimensions, a point in a
cube requires 3 coordinates.
What is Principal Component Analysis?
A dimension reduction method that helps visualize the relationship between different variables when
there are a lot of dimensions to measure. Points that are closer are more similar and points that are
further are less similar with the x-axis describing more change.
What are the risks of EDA?
Spurious association, bad data, bad presentation, bad taste, bad perception
What is perception?
Perception is the organization, identification, and interpretation of sensory information in order to
represent and understand the presented information or environment.
What influences perception?
Background: We can distinguish between light shades of grey when they are on a light background better
than when they are on a dark background
Neighborhood: We can perceive relative brightness of colour quite well, but not absolute brightness or
colour
Describe how colour can be perceived as quantitative information (perception)?
Colours are thought to be a scale with accurate mapping of quantitative information. Expect that there is
information in the colours.
What are the factors that affect perceptual distance in colour palettes
