How do you find the range of a data set?
Range is the difference between the highest and the lowest values in a given set of observations.
Answer: We can find the range of a data set by subtracting the lowest value from the highest value in a set of observations.
Let's look into an example to understand this.
Range = Highest value - Lowest value
The weight of 5 students are given below in kgs:
10, 12, 15, 17, 18
Highest observed weight = 18 kg
Lowest observed weight = 10 kg
Hence, Range of the weight = 18 –10 = 8 kg
Therefore, we can find the range of a data set by subtracting the lowest value from the highest value in an observation.
