Question

how is the quantile() function in r used to compute percentiles? by calculating the difference between the maximum and minimum values in the by summing the values in the data set and dividing by the number of values. by providing the data set and the desired percentiles as arguments. 4. by finding the square root of the values in the data set.

Explanation:

The quantile() function in R is used to calculate quantiles (including percentiles) of a data set. To compute percentiles, you provide the data set and the desired percentiles (as values between 0 and 1) as arguments. For example, if you have a vector x and you want to find the 25th, 50th, and 75th percentiles, you would use quantile(x, c(0.25, 0.5, 0.75)).

• The first option (calculating the difference between max and min) is for the range.
• The second option (summing and dividing by the number of values) is for the mean.
• The fourth option (finding the square root) is not relevant to computing percentiles.

Answer:

By providing the data set and the desired percentiles as arguments.
