In a field lives a population of rare Grasshoppers. The field is a square 100m by 100m. The Grasshopper International Trust (GIT) plan to carry out a survey to discover how many Grasshoppers live in the field.
The GIT are very short-staffed at the moment due to the ‘Cricket Crunch’ and can’t survey the whole field. They decide to break the field in to smaller squares as shown:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 100m 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 100m
Discuss how the GIT could estimate the total Grasshopper population without looking at the entire field. • How accurate are their results likely to be? • How could they make their results more accurate?
