X ~ U(0,1)
Find the 1st quartile or 25th & the 3rd quartile
75th percentile and the median.
Help me please
X is uniformly distributed in the interval (0,1).
The pdf (probability density function) of X is
The cdf (cumulative distribution function) of X is
The first Quartile, Q1, is the value of X, such that 25% of the values are below X=Q1. In other words, the probability that X is less than or equal Q1 is 0.25
The Third Quartile, Q3, is the value of X, such that 75% of the values are below X=Q3. In other words, the probability that X is less than or equal Q3 is 0.75
The Median, M, is the value of X, such that 50% of the values are below X=M (and 50% are above X=M). In other words, the probability that X is less than or equal M is 0.50
