You put the numbers in order from least to greatest then, start at the beginning and end, and cross out one... two... three... four..., then so on, until you have only one number in the middle.
Example 27,44,45,46,52; cross out 27, then... 52, then... 44, then... 46, then... 45 is the last answer left, so 45, is your answer.
man, whoever answered this question is a total fool. they wanted to know how to find the median of GROUPED DATA not just the median.
wow what a fool.

Median formula for grouped data?
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.
How you can find the median of grouped data graphically?
On the cumulative frequecy diagram, find 50% on the frequency [usually, vertical] axis. Draw a line to the graph and then drop a perpendicular to the other [horizontal] axis. Where it hits the second axis is the median value.
Why it is useful to fiNd the meaN mediaN aNd mode of a set of data?
when there are extreme values in the data
How do find the interquartile range in your data?
Arrange the data in increasing order and count the number of data points = N. Find the integer K = N/2 or (N+1)/2. The Kth number in the ordered set is the median. Now consider only the numbers from the smallest to the median and find the median of this subset. This is the lower quartile = Q1. Then consider only the numbers from the original median to the largest. Find the median of this subset. It is the upper quartile = Q3. Then IQR = Q3 - Q1
How do you find the median with an even data set?
Let the data set be 3,4,5,6,7,8. First put the data in rank order ; already done!!!! To find the MEDIAN , we tak the two middle numbers, '5' & '6' in this case. Then (5 + 6) / 2 = 11/2 = 5.5 5.5 is the Median.
How is a frequency distribution used?
it is used to find mean<median and mode of grouped data

Which graphic display shows the median and data spread about the median?
A frequency diagram or, for grouped data, an histogram.
How can you find mean median and mode for GROUPED data?
Mean, median and mode are ways to find averages. The mode is the most common answer in a set of data. The median the number that is in the middle when the numbers are put in order. The mean is the statical average.
How you can find the median of grouped data graphically?
On the cumulative frequecy diagram, find 50% on the frequency [usually, vertical] axis. Draw a line to the graph and then drop a perpendicular to the other [horizontal] axis. Where it hits the second axis is the median value.
Which measures of central location always have only one value for a set of grouped or ungrouped data?
Mean and median are the measures of central location that always have one value. This is true for a set of grouped or ungrouped data.
How can you find the assumed mean of grouped data?
find assumed mean data is 46,55,52,59,63,47,56,50,51,55 ,
What is a quartile in a math problem?
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.
Can a grouped of data be grouped?
Not sure what a "grouped of data" means!
How do you find the first quartile in grouped data?
Can ypu find the mean and median with data from a histogram?
You can estimate the median and the mean.
Can the median be used to describe both categorical data and numerical data?
Can the median and mode be used to describe both categorical data and numerical data
