5. Tell whether the statement is true or false:
(i) The mode is always one of the numbers in a data.
(ii) The mean is one of the numbers in a data.
(iii) The median is always one of the numbers in a data.
(iv) The data 6, 4, 3, 8, 9, 12, 13, 9 has mean 9.
(i) True.
Mode is the observation which occurs maximum number of times.
Hence, Mode will always be the one of the numbers in a data.
(ii) False.
(iii) False.
For even number of observations, the median is the mean of the and values.
(iv) Mean =
Hence, the statement is False.
1. True,mode is the no of most occurring observation that's why mode is always a no. Of data
2. False,it may be but not compulsory
3. False , because in even observation it is average of middle no.
4. False ,mean is not 9
