To find the missing number when the median is given, you first need to determine the total number of values in the data set. If the total number of values is odd, the median will be the middle value. If the total number of values is even, the median will be the average of the two middle values. Once you have identified the median, you can work backward to determine the missing number based on its position relative to the median.
If there is no mean it is very rare that you will be able to find a missing number. Potentially if you have other numbers and you have a mode you can deduce the missing number by using the mode (if there needs to be one more of a certain number or a certain number cannot be increased in its count of numbers i.e. you can't have more 6's to maintain the current mode).
The median uses the position of the data rather than their actual values. As a result, in general, you will only be able to determine whether the missing value is greater than or less than the median.
To find the median from a frequency table, first determine the total number of observations by summing the frequencies. Then, identify the median position, which is the middle value (or the average of the two middle values if the total is even). Locate the cumulative frequency that reaches or exceeds this median position, and the corresponding value in the data range is the median. If necessary, interpolate between values for a more precise median.

How do you find missed frequency if median and mode are given
To find the missing number when the median is given, you first need to determine the total number of values in the data set. If the total number of values is odd, the median will be the middle value. If the total number of values is even, the median will be the average of the two middle values. Once you have identified the median, you can work backward to determine the missing number based on its position relative to the median.
Given the median and trapezoid MOPN, what is the value of x?

To find the median from a frequency table, first determine the total number of observations by summing the frequencies. Then, identify the median position, which is the middle value (or the average of the two middle values if the total is even). Locate the cumulative frequency that reaches or exceeds this median position, and the corresponding value in the data range is the median. If necessary, interpolate between values for a more precise median.
Simple answer:Divide the total number of observations (plus 1, if small) by 2 to find the middle rank.Look at the cumulative frequencies for the grouped data and find the group in which the middle rank would appear. That is the median group.More sophisticated answer:Withing the median group, interpolate.
To find the median temperature over a given period of time, arrange the recorded temperatures in numerical order and take the value in the centre.
A quartile is a given section in a range of data. To find the quartile, you must first find the median. Then find the "median of the median", using these to separate your data into sections, giving you a total of four sections of data.
