take the sum of all the numbers ∑x
and divide it by the number of numbers in the data set. nor ∑x/n
whats does astonshing mean?.
find assumed mean data is 46,55,52,59,63,47,56,50,51,55 ,
The mean of a set of data is the sum of that data divided by the number of items of data.
whats mean astonish in dictionary?
im tring to find out myself whats it mean
to find the mean of a set of numbers you have to find the total sum of the data divided by the number of addends in the data.
To answer this question I will use an example. Data set: 10, 20, 30, 40, 50. First find the sum of all the numbers...so 10+20+30+40+50= 150. Then you take the sum (150) and divide it by the number of numbers in the data set. So 150 divided by 5 (the number of numbers in this data set) = 30. 30= the mean of the above data set. Finding the mean is pretty simple. :)
well because in the mean you have to add them and its different from the median and the mode
One reason I can think of why you might not be able to find the mean of numerical data would be if there were missing data points.
no
To find the first deviation of a dataset, you first calculate the mean (average) of the data points. Then, for each data point, subtract the mean to find the deviation from the mean. The first deviation is typically the result from the first data point, which is the difference between that data point and the mean. This process helps in understanding how each data point varies from the average.
To calculate the mean absolute deviation (MAD) of a data set, first find the mean of the data. Then, subtract the mean from each data point to find the absolute deviations. Finally, take the average of these absolute deviations. If you provide the specific data set, I can help calculate the MAD for you.
