    Frequency tables and histograms.

    Hello

    Can I please have help with the following questions:

    Q.1 How do you find the median from a frequency table (below suppose to be a table):
    score: 15 20 25 30 35 40 45 50
    Frequency: 2 3 7 8 8 7 3 2

    Q.2How do you find the mean of a Frequency Histogram by using the mid-point of each class interval?

    Thank you
