4.3 Quadrates Sample


  • The population of daisy. Sample has to be random so there is NO BIAS.
  • The sampling has to be representative, have ti take sample large enough that are estimate to the population to the true population enough.
  • The grid must be equal sizes. Place the quadrates in squares and we need to find our random numbers. So, we could put our quadrates then count the number of daisy.
  • We need the representative sample which are bigger the better, we should look 10 quadrates but about 10% of the actual area would be even more appropriate. As we collect our data and generate the column as the number of daisy.
  • To complete this we add up the column and divided by the daisy of quadrates and you would get the number of daisy per metre square.
