Answer 2

Mean is the measure of central tendency obtained by calculating the sum of values and dividing the figure by the number of values there in the data.

Measures of Central tendency-

The measures of central tendency help in finding the average, middle of a data set. Some of the common measures of the central tendency are mean, mode and median.

• Mean or Arithmetic mean is the sum of all values divided by the number of values.

The formula for mean:

Mean ($\bar x$)= sum of x/ number of observations

where x is the observations for a given data.

• Mode is known as the most frequently occurring value in an observation.
• Median is calculated by finding the middle value of an ordered set.
• Range of data is the difference between the largest and smallest value of an interval.
• The sum of the data is simply the addition of all the observations in a given data.
• Dispersion is the limit to which data can be squeezed.

Thus, the arithmetic mean is the measure of central tendency obtained by calculating the sum of values and dividing the figure by the number of values there in the data.
