[amp_mcq option1=”Number of classes in a continuous distribution” option2=”Size of class limits” option3=”Direction of the classification” option4=”None of the above” correct=”option3″]
Sturge’s rule is used to find the approximate number of classes in a continuous distribution. It states that the number of classes should be equal to $1 + \log_{10}(n)$, where $n$ is the number of observations.
Option A is incorrect because Sturge’s rule is not used to find the number of classes in a discrete distribution.
Option B is incorrect because Sturge’s rule is not used to find the size of class limits.
Option C is incorrect because Sturge’s rule is not used to find the direction of the classification.
Option D is the correct answer because Sturge’s rule is used to find the approximate number of classes in a continuous distribution.
