EMPIRE™ Turf Research | Statistical Significance In Mowing Rates Difference

The following tests show the statistical significance in the difference in the mowing rates, and have been derived from a market research program.

The purpose of the research was to test the theory that there were differences in the mowing rates for Kikuyu & Couch compared to Empire Turf.

The following tests prove that there is a significant difference in mowing rates for the three different varieties.

  • TEST 1
    Kikuyu compared to EMPIRE™ Turf – fertilised twice per year
  • TEST 2
    Couch compared to EMPIRE™ Turf – fertilised twice per year
  • TEST 3
    Kikuyu compared to EMPIRE™ Turf – fertilised once per year
  • TEST 4
    Couch compared to EMPIRE™ Turf – fertilised once per year
  • TEST 5
    Kikuyu compared to EMPIRE™ Turf – under moderate wearing conditions

The purpose of a means test is to compare the size of the difference between two means in relation to the amount of inherent variability (the random error) in the data. If the random error is large then we are unlikely to find a significant difference between means unless this difference is also very large.

The paired T tests use standard deviation and the mean (or average) for the mowing rates to compare the difference in mowing.
