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
The median is the mean of the middle two. For example, find the median of the set {1, 3, 4, 6, 9, 10, 15, 20}. There are 8 items in the data set, so the median is the mean of the middle two. The middle two are the 4th and 5th data items: 6 & 9 median = mean of 6 & 9 = (6 + 9)/2 = 7.5
No, not all data sets have a mode but all data sets have a mean and median.
Mean = a + [
