MeanofUngroupedData: Ungroupeddata is the type of distribution where individual data is presented in a raw form. The mean of data shows how the data are scattered throughout the central part of the distribution. Hence, the arithmetic numbers are called the measures of central tendencies.
Arithmeticmean (AM) is one of the measures of central tendency which can be defined as the sum of all observations divided by the number of observations. Formula to find arithmeticmean :
The meanofdata indicate how the data are distributed around the central part of the distribution. That is why the arithmeticnumbers are also known as measures of central tendencies.
You will learn about arithmeticmean, formula for ungrouped and grouped data along with solved examples/questions, followed by properties, advantages, disadvantages and so on.
Mean for ungrouped data, also known as the Arithmetic Mean (often just called the “mean”) is the most common type of average. It is obtained by adding all the observations and dividing the total by the number of observations.
The arithmeticmean, often simply referred to as the mean, is a very common statistical measure. It is calculated by adding up all the values in the data set and then dividing by the number of values. For unclassified data, the formula to calculate the arithmeticmean is: x ¯ = 1 n ∑ i = 1 n x i
The arithmeticmean of different observations for any set of tests or experiments which is ungrouped can be used to represent the whole as a one valued observation.
The mean of data indicate how the data are distributed around the central part of the distribution. That is why the arithmetic numbers are also known as measures of central tendencies.
