  • Q1

    Co-efficient of range is calculated by the formula

    Marks:1
    Answer:

    (L - S)/(L + S)

    Explanation:

    To compare the variability of two or more distributions given in different units of measurement, co-efficient of range is used. It is obtained by applying the formula,

    Co-efficient of range = (L - S)/(L + S)

  • Q2

    Inter-quartile range equals

    Marks:1
    Answer:

    Q3– Q1

    Explanation:

    Inter-quartile range is based upon middle 50% of the values in a distribution. Therefore, Q- Q1 is the formula used to calculate inter-quartile range.

  • Q3

    Quartile deviation is equal to

    Marks:1
    Answer:

    (Q3 - Q1)/ 2

    Explanation:

    Quartile deviation refers to the midpoint of the inter-quartile range. It is an absolute measure of dispersion.

    It is obtained by the formula,

    Q.D = (Q3 - Q1)/2

  • Q4

    Coefficient of quartile deviation, with Q1 = 20 and Q3 = 60 is equal to

    Marks:1
    Answer:

    0.50.

    Explanation:

    Coefficient of Quartile Deviation = (Q3 - Q1)/ (Q3 + Q1) = (60 - 20)/ (60 + 20) = 40/80 = 0.5

  • Q5

    The co-efficient of range, with the smallest value of a series at 20 and the largest value at 30, equals

    Marks:1
    Answer:

    0.2.

    Explanation:

    Coefficient of Range = (L- S) / (L + S) = (30 - 20) / (30 + 20) = 0.2
