What is the formula to calculate middle 60% range?
a. P90-P10
b. Q3-Q1
c. P80-P20
d. P90-P30
Answers
Answer:
The formula to find the midrange = (high + low) / 2.
Answer : b. Q3-Q1
Explanation :
The middle 60% range is a measure of the spread of data within a dataset. It is calculated by subtracting the first quartile (Q1) from the third quartile (Q3).
Q1 and Q3 are measures of central tendency that divide a dataset into four equal parts (or quartiles). Q1 represents the data point that separates the lowest 25% of the data from the highest 75% of the data, while Q3 represents the data point that separates the lowest 75% of the data from the highest 25% of the data. By subtracting Q1 from Q3, we are essentially measuring the spread of the middle 50% of the data, which is why it is referred to as the middle 60% range.
The formula to calculate the middle 60% range is:
Middle 60% range = Q3 - Q1
It's worth noting that other methods to measure the spread of data such as interquartile range (IQR) and standard deviation may be used as well depending on the context and the requirement of analysis.
Other options, such as P90-P10, P80-P20, and P90-P30, are not used to calculate the middle 60% range as they do not represent the middle 50% of the data. P90 and P10 represent the 90th and 10th percentiles respectively and P80 and P20 represent 80th and 20th percentiles respectively.
