Question

For a 5-class system of mapping, what will be the class-break values (largest number in the dataset is by default the upper bound of the classification; round all class breaks to nearest integer) if you use the following alternative methods of classifying these values? Here is a list of values: 20, 40, 118, 126, 39, 145, 23, 93, 267, 102, 16, 54, 32, 78, 65.

1. Equal interval method:      
2. Quantile method:              
3. Natural Breaks.     

Answer 1

TheGiven nfomation 102, 16, S4,32, 18,65 owest is 16 highest is a67 Hence class Susterv 女 6 50.& >class break. Values will be 50' 2+116.4 = 166 , 6

uan le method Total no of value is16 Hence ach ch will have3 ale he values are23.40, 78, 8 64, Natura, breaks :- 26,14S, a67, 109,78
