Web18 aug. 2024 · In a perfectly symmetrical distribution, the mean and the median are the same. This example has one mode (unimodal), and the mode is the same as the mean and median. In a symmetrical distribution that has two modes (bimodal), the two modes would be different from the mean and median. Web1 sep. 2024 · Mean is defined as the ‘central’ value of the given set of data whereas median is the ‘middle-most’ value in the given set of data. An ideal measure of central tendency is one which is clearly defined, easily understood, simply calculable.

Web7 feb. 2024 · Since 15 is one of the choices, it is the correct answer. Alternate Solution: We observe that depending on the value of y, the median is either 5 (if y is less than or equal to 5), y (if y is between 5 and 9) or 9 (if y is greater than or equal to y). If the median is 5, then, since the mean is also 5, the sum of the five numbers must be 5 x 5 ... WebThe mean is affected by outliers that do not influence the mean. Therefore, when the distribution of data is skewed to the left, the mean is often less than the median. When the distribution is skewed to the right, the mean is often greater than the median. In symmetric distributions, we expect the mean and median to be approximately equal in ...
