And 10625 The suggested interval size of the class intervals for a histogram can be estimated by?

Answer 1

The suggested interval size for class intervals in a histogram can be estimated using Sturges' formula, which is ( k = 1 + 3.322 \log(n) ), where ( n ) is the number of data points. Another method is to use the square root choice, which suggests using the square root of the number of observations as the number of intervals. Additionally, the range of the data divided by the desired number of intervals can provide a suitable interval size.
