20
Q

How is random sampling carried out

A
  • divide the study area into a grid of numbered lines
  • obtain coordinates using a random number generator
  • take samples from the coordinates

What is the Median, Mean and Mode

A

Median -
Mean -
Mode -

23
Q

What is the standard deviation

A

the range of values either side of the mean

24
Q

What does it mean if the standard deviations overlap

A

there is no significant difference between the variables

25
Q

Why is the standard deviation a better measurement than range

A

standard deviation takes into account the variable data therefore influences can be made
