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.
You can estimate the median and the mean.
You can estimate them both.
You can estimate them both.
To find the mean, you all them all up and divide by how many ever there are. To find the median, you put them in order and the middle one is the median. If there are an even number of data, you take the two in the middle, add them together, then divide by 2.
Mean = a + [
it is used to find mean<median and mode of grouped data
find assumed mean data is 46,55,52,59,63,47,56,50,51,55 ,
You can estimate the median and the mean.
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.
when there are extreme values in the data
You can estimate them both.
You can estimate them both.
To find the mean, you all them all up and divide by how many ever there are. To find the median, you put them in order and the middle one is the median. If there are an even number of data, you take the two in the middle, add them together, then divide by 2.
Suppose you compare the mean of raw data and the mean of the same raw data grouped into a frequency distribution. These two means will be
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.
No, not all data sets have a mode but all data sets have a mean and median.
Mean = a + [
