What statistical technique is best used to test a distribution pattern?
Chi - square
Pearsons Product
Spearmans rank
Nearest neighbour
How many samples do you need to conduct a nearest neighbour analysis?
12
20
30
15
Why is the coefficient of variation sometimes a better way to compare data sets than standard deviation?
Percentages are easier to compare
It uses mean values
It can be plotted on a scattergraph
It can be used in a linear regression
What is a common problem when using pearsons product?
Small sample
Human error
Tied ranks
Negative values
What test could be used to establish differences in land use by postcode?
Chi-square
Spearmans rank
Pearsons product
Standard deviation
What is a common issue influencing the reliability of a chi-square test
Observed frequencies below 5
Total observations of 20 or more
Expected frequencies below 5
Total observations of less than 30
One disadvantage of using a proportional symbol map is...
Creating a reasonable scale
Fitting everything on the map
Differences can be exaggerated
You need to create percentages
One advantage of using a choropleth map is...
Comparing regions becomes simple
It uses precise values
You don't need to calculate distributions
It is simple to create
A disadvantage of using a dot distribution map is...
It can obscure patterns in sparsely populated areas
It can obscure patterns in densely populated areas
It can be difficult to compare large areas
It can be difficult to compare small areas
An advantage of using a flow map is...
It is easy to create the scale
It can establish not just amounts but directions
It can be completed using pie charts
It can be completed using bar charts
A dispersion diagram could be used to support
Standard deviation
Modal groups
Spearmans rank
Pearsons product
A line graph can be accurately plotted using
Spearmans rank
Scatter graphs
Linear regression
Dot distribution
A polar graph shows
Distributions by time
Distributions by area
Distributions by direction
Distributions by land use
A flow diagram can be used to show
Systems or cycles
Direction
Vastly different values
