set all you numbers up in order from smallest to largest. then find the middle. if there are two number in the middle, add them up and divide by two. Example: set of numbers - 8,6,3,4,10,15,36 put in order from smallest to largest - 3,4,6,8,10,15,36 now find the middle number - 8 8 is then my median of this sequence

How do you calculate median using linear interpolation in an O-give curve?
To calculate the median using linear interpolation in an O-give curve, first identify the total number of observations (N) and find the median position, which is ( \frac{N + 1}{2} ). Locate this position on the cumulative frequency curve (O-give) and determine the corresponding cumulative frequency value. If the median position falls between two cumulative frequency points, use linear interpolation to estimate the median value by finding the x-values (data points) associated with these frequencies and applying the formula for interpolation.
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.
How to find a cumulative percent in a pareto chart?
cumulative percentage = (cumulative frequency ÷ n) x 100
How do you find out the cumlative frequancy?
Cumulative frequency is found by adding the frequency of each class interval to the sum of the frequencies of all previous intervals. To calculate it, you start with the first interval, where the cumulative frequency is simply the frequency of that interval. For subsequent intervals, you add the frequency of the current interval to the cumulative frequency of the previous interval. This process continues until all intervals are accounted for, resulting in a cumulative frequency distribution.
What is the median of a single value?
The median is the number in the middle. You find the median, by putting the values in order from lowest to highest, then find the number that is exactly in the middle. If you only have a single value, one could argue that it is in the middle. That would make the single value the median. One could also argue that there no numbers on either side to the definition makes no sense and there is no median of a single value.

What is utility of cumulative frequency curve?
The main utility of a cumulative frequency curve is to show the distribution of the data points and its skew. It can be used to find the median, the upper and lower quartiles, and the range of the data.
How do you find cumulative frequency?
By adding up the (one by one,) the frequency total in order to find the cumulative frequency, most commonly, you just then plot this on a cumulative frequency graph or box plot.
How to find a cumulative percent in a pareto chart?
cumulative percentage = (cumulative frequency ÷ n) x 100

Define cumulative frequency?
You just need to add up the frequency total one by one to find the cumulative frequency of a certain set of data.
How do you get the median of a continuous random variable?
You integrate the probability distribution function to get the cumulative distribution function (cdf). Then find the value of the random variable for which cdf = 0.5.
What are the advantages and disadvantages of median?
Median cannot be used for qualitative data (a mode can).The sampling distribution of the median is complicated (the mean is well studied).Median can usually be used for data that can be ordered without there being a ratio scale. For example, "small-medium-large", or "very negative-negative-neutral-positive-very positive". A mean cannot be calculated without arbitrarily assigning a numerical value to the terms.A median is not dependent on all the values which means that it is not distorted by outliers (extreme values).It is easy to find the median value from cumulative frequency charts.

Purpose of cumulative frequency?
Cumulative Frequency - The purpose is to help understand the total frequency of everything UP TO a given value. By example: You could have a list of women heights and the frequency (or probability or fraction of the population) that you'll find women of each height. Or you could have a list of women heights and the frequency that you'll find women of that height OR SHORTER. This is "cumulative" in that it adds all the frequencies from zero up to that point. Often cumulative frequency is shown in a graphic rather than as a list of values as above. You might have the axis on the left (Y-axis) go from 0% to 100% and the horizontal axis on the bottom (X-axis) go from 0 cm to 300 cm. The line on the chart would show the percentage of women with heights at or under that X-value, and of course, it would be very close to 0% up to 100cm (assuming adult women), then increase to nearly 100% at 200cm, and be flat at 100% up to 300cm.
