    Data Handling

    • The middle value of the given observation is called the median.
    • The value that occurs most frequently in the given data is called the mode.
    • The mean of the first 5 prime numbers is (2 + 3 + 5 + 7 + 11) / 5 = 28 / 5 = 5.6.
    • The difference between the highest and lowest observation is called the range of the given data.
    • The average of the given observations is called the mean.
    • The median of the marks is 39, and the mode is 38 and 39.
    • The mean, median, mode, and range of the price of apples varied over a period of months need to be calculated.

    Fractions and Decimals

    • The reciprocal of 7/2 is 2/7, of 11 2/3 is 3/11, and of 20/5 is 5/4.
    • The product of:
    • 2/3 and 9/4 is 3/2
    • 1 ½ and 3 ½ is 5 ¼
