The data's median is the dataset's middle value. The median value shows that 50% of the data values are less than or equal to the median value, and 50% of the data values are greater than or equal to the median value.

Option b is correct since half of the observations in the dataset are greater than the median value.

What are half of the observation always greater than?

Answer and Explanation: According to the definitions above it is clear that the median is the value such that there are an equal number of values above and below it. Therefore, the number of observations that are less than the median = Number of observations that are more than median.

What is the value that has half of the observations above it and half?

The median is that value that has half the observations above it and half below.

What is the value in the data set for which half of the observations are greater and half of the observations are fewer?

The median M is the midpoint of a distribution, the number such that half of the observations are smaller and the other half are larger. To find the median of a distribution: 1. Arrange all observations from smallest to largest.

Are half the observations on either side of the mean?

The median is the middle value in distribution when the values are arranged in ascending or descending order. The median divides the distribution in half (there are 50% of observations on either side of the median value). In a distribution with an odd number of observations, the median value is the middle value.
