Detailed explanation-1: -The affirmation is true. The second quartile value is equal to the median. The second quartile is the bottom 50% or the median.
Detailed explanation-2: -Yes, I agree with the statement. It is the value that divides the series into two equal parts, so that the number of items above it, is equal to the number of items below it. It is not affected by extreme values. Median = n/2 and Q = 2 (n/4) i.e n/2. Therefore, the Median is equal to the second quartile.
Detailed explanation-3: -Q2 is of course always equal to the median (in this case 155). The first quartile is the 25th percentile and the third quartile is the 75th percentile; the formula to compute percentiles (presented later) can be used to calculate quartiles.
