Find The Mean Of The Following Data By Direct Method. Find the mean of the following data using direct method. Hence the required arithmetic mean for the given data is 45.
4 marks Hence the mean of the above data is 344 marks. X Σ f m Σ f o r X 3440 100 X 34. If x 1 x 2 x n are observations with respective frequencies f 1 f 2 f n then this means observation x 1 occurs f 1 times x 2 occurs f 2 times and so on.
Find the average weight.
If x 1 x 2 x n are observations with respective frequencies f 1 f 2 f n then this means observation x 1 occurs f 1 times x 2 occurs f 2 times and so on. In this method find the class marks of class interval. Calculate the arithmetic mean from the following data. F n x n and the number of observations f 1 f 2.
