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.
find the frequency before finding the percent total -_- :)
The lower boundary of the median class in a frequency distribution is the smallest value that defines the class interval containing the median. To find it, you first determine the cumulative frequency and identify the class interval where the median lies, which is typically the class with a cumulative frequency that exceeds half of the total frequency. The lower boundary is then the starting point of that specific class interval.
You find the total of all the frequencies, N. Then the percentage for any frequency is 100*frequency/N.
The median can be found out by drawing a perpendicular to the x-axis from the intersection point of both the ogives
First, you need a frequency table.
How do you find missed frequency if median and mode are given
find the frequency before finding the percent total -_- :)
it is used to find mean<median and mode of grouped data
A frequency table is not something that one can purchase. This is a mathematical table that is used for statistics. One can find much more detail about frequency tables on the Wikipedia website.
You find the total of all the frequencies, N. Then the percentage for any frequency is 100*frequency/N.
the table
bum fun fun
The best time to use a frequency table is when you have disorganized raw data, that need to be sorted, usually to find trends in the data.
