Average This is the arithmetic mean, and is calculated by **adding a group of numbers and then dividing by the count of those numbers**. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5.

The domain of a function is **the set of values that we are allowed to plug into our function**. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

Average This is the arithmetic mean, and is calculated by **adding a group of numbers and then dividing by the count of those numbers**. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5.

**The mean** (also called arithmetic mean), in everyday language called the average, is the sum of the values of a group of numbers divided by the amount of numbers in the group.

Once you have all the numbers for each month, **add all the numbers together for each month, and then divide them by the total amount of months**.

Average This is the arithmetic mean, and is calculated by **adding a group of numbers and then dividing by the count of those numbers**. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5.

There are three different types of average. These are called **the mean, the median, and the mode**. Each one gives slightly different information.

Mode: The most frequent number—that is, **the number that occurs the highest number of times**. Example: The mode of {4 , 2, 4, 3, 2, 2} is 2 because it occurs three times, which is more than any other number.

It can be calculated for a country by dividing the country's national income by its population.. We use averages **because they are useful for comparing differing quantities of the same category**.

Method: **Aggregate value is calculated by adding all values together**. Average value is calculated by adding all the values together and dividing by the number of elements.

We consider there to be four types of average: **mean, mode, median and range**. Actually, range is a measure of spread or distribution but the others are our most common “measures of central tendency”.

Assuming that the first natural number is 1, then the average = 150(151)/ = **75.5**. (If you count 0 as a natural number, then the average is (150(151)/ = 75.

But whenever an average is used to represent an uncertain quantity, it ends up distorting the results because **it ignores the impact of the inevitable variations**. Averages routinely gum up accounting, investments, sales, production planning, even weather forecasting.

Median, partition value and mode are **positional averages**. This option is the correct answer.

Mathematical average refers to all such average where a figure is taken out through mathematical methods from the a given series that represents the whole series. These average includes **arithmetic mean, geometric mean and harmonic mean**.

Positional average refers to **the average which are taken out through observation from the series where a particular value from the series is picked up which represents the whole series**. In median, the middle most value of the series is taken as the representative value. Therefore, median is a positional average.

The mode is **the value that appears most frequently in a data set**. A set of data may have one mode, more than one mode, or no mode at all. Other popular measures of central tendency include the mean, or the average of a set, and the median, the middle value in a set.

**The median can be used to determine an approximate average, or mean**, but is not to be confused with the actual mean. If there is an odd amount of numbers, the median value is the number that is in the middle, with the same amount of numbers below and above.

We use averages as they are **useful for comparing differing quantities of the same category**. There are limitations of calculating averages because this does not give any information about the distribution of a thing between people. For example, the per capita income does not show the distribution of income.
