    O man....I said to check your answers only! This is for accuracy only. Many times you get your answer wrong bcz you aren't accurate. Btw it's not that they aren't allowed. Have u done Statistics (4040)?

    Assume if this is the table given to you....how would you find Q1, median and Q3. 85.5-90.5 -6 90.5-95.5 -4 95.5-100.5 -10 100.5-105.5 -6 105.5-110.5 -3 110.5-115.5 -1 The digits after the ranges of values are the frequencies. Solve it so that I can elaborate to you how to do it rightly.

    Nah.....the graph is a curve and it's not necessary that Q1 is exactly half of the median. For example the total frequency is 100, the median would be the 50th value. By halving it, the Q1 would be the 25th value. So for finding Q1......you can plot lines on the graph and check the corresponding...

    Remember...these formulas are only for checking your answer and for accuracy. You should necessarily plot the lines on the graph.
