The mean number of students in a classroom at school A is 32.5 and there are 25 classrooms. The mean number of students at school B is 29.6 in 12 classrooms. At school C the mean in each class is 15.3 for 10 classrooms. What is the mean number of students per classroom for all the schools combined? This calculator calculates averages better than the average calculator. Also known as a mathematical mean, the average is the sum of all numbers divided by the number of numbers summed. The mean is an extremely common ( and as it turns out, extremely useful ) mathematical concept. Begin by entering the numeric values into the new number input box.

Calculator Use

Calculate mean, median, mode along with the minimum, maximum, range, count, and sum for a set of data.

Enter values separated by commas or spaces. You can also copy and paste lines of data from spreadsheets or text documents See all allowable formats in the table below.

What are Mean Median and Mode?

Mean, median and mode are all measures of central tendency in statistics. In different ways they each tell us what value in a data set is typical or representative of the data set.

The mean is the same as the average value of a data set and is found using a calculation. Add up all of the numbers and divide by the number of numbers in the data set.

The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median. If there are 2 numbers in the middle, the median is the average of those 2 numbers.

The mode is the number in a data set that occurs most frequently. Count how many times each number occurs in the data set. The mode is the number with the highest tally. It's ok if there is more than one mode. And if all numbers occur the same number of times there is no mode.

How to Find the Mean

1. Add up all data values to get the sum
2. Count the number of values in your data set
3. Divide the sum by the count

The mean is the same as the average value in a data set.

Mean Formula

The mean x̄ of a data set is the sum of all the data divided by the count n.

[ text{mean} = overline{x} = dfrac{sum_{i=1}^{n}x_i}{n} ]

How to Find the Median

The median ( widetilde{x} ) is the data value separating the upper half of a data set from the lower half.

• Arrange data values from lowest to highest value
• The median is the data value in the middle of the set
• If there are 2 data values in the middle the median is the mean of those 2 values.

Median Example

For the data set 1, 1, 2, 5, 6, 6, 9 the median is 5.

For the data set 1, 1, 2, 6, 6, 9 the median is 4. Take the mean of 2 and 6 or, (2+6)/2 = 4.

Median Formula

Ordering a data set x₁ ≤ x₂ ≤ x₃ ≤ .. ≤ x_n from lowest to highest value, the median ( widetilde{x} ) is the data point separating the upper half of the data values from the lower half.

If the size of the data set n is odd the median is the value at position p where

[ p = dfrac{n + 1}{2} ] [ widetilde{x} = x_p ]

If n is even the median is the average of the values at positions p and p + 1 where

[ p = dfrac{n}{2} ] [ widetilde{x} = dfrac{x_{p} + x_{p+1}}{2} ]

How to Find the Mode

Mode is the value or values in the data set that occur most frequently.

For the data set 1, 1, 2, 5, 6, 6, 9 the mode is 1 and also 6.

Interquartile Range

IQR = Q₃ - Q₁

Outliers

Potential Outliers are values that lie above the Upper Fence or below the Lower Fence of the sample set.
Upper Fence = Q₃ + 1.5 × Interquartile Range
Lower Fence = Q₁ − 1.5 × Interquartile Range

How to Calculate Equivalent Ratios

As we previously mentioned, Equivalent Ratios are two ratios that express the same relationship between numbers. The Equivalent Ratio Calculator provides a table of equivalent ratios that have the same relationship between each other and directly with the ratio you enter into the calculator. We will look at how to calculate equivalent ratios shortly, first lets look at how to use the free online equivalent ratio calculator:

1. Enter a Ratio into the equivalent ratio calculator, for example, you could enter 7:25
2. Select the number of equivalent ratios that you would like to see in the table of results
3. The equivalent ratio calculator will calculate as you type and produce a lis of equivalent ratios in a table below the calculator
4. [Optional] Print or email the Table of Equivalent Ratios for later use

As we can see, using the equivalent ratio calculator is a quick and easy way to calculate equivalent ratios. This is useful for quick math but you may wish to calculate equivalent ratio manually. That great, understand math formula and calculations is important, particularly ratio math as ratios are used in a significant number of business calculations, finance calculations and general day to day calculations, for example: miles per hour, your BMI, the amount of money your share or sweets you share with friends, these are all good examples of ratios. If you are still working on your mental arithmetic and manual ratio calculations, we suggest that you first enter the ratio into the calculator to see the results, then complete the manual math using the equivalent ratio formula. This way you can check your answers and build up your confidence.

How to Manually Calculate Equivalent Ratios

When calculating equivalent ratios it is important to understand that mathematically, you are expressing the same relationship, simply in different amounts. for example, if you have 10 sweets to share with 4 friends, this is the same and having 5 sweets to share with 2 friends in ratio terms. Although the quantities vary, the ratio of the numerator and denominator are the same (both can be divided by 2 in this instance). The important point to remember is that equivalent literally means equal, so what you are calculating is the same ratio expressed in different quantities. This can only be achieved via multiplication of division.

As equivalent ratios have the same value there is technically no equivalent ratio formula but the following equivalent ratio formula will help you with the manual math calculations.

We have previously covered the numerator and denominator in the Fractions Calculator, if you are not familiar with the numerator and denominator or simply wish to refresh your memory please review that article and supporting calculator before proceeding.

where

• n = numerator
• d = denominator
• a = multiplier

In our equivalent ratio formula, we can see that by multiplying both the numerator and denominator by the same amount (a) that we maintain the relationship with all equivalent ratio and our initial ratio from which we started the calculation

What is a ratio?

A ratio is a direct comparison of one number against another. A ratio calculator looks to define the relationship that compares between those two numbers

Where are Ratio Calculations Used?

Ratios are used everywhere, from cooking with your favourite recipes to building housing, here are some common applications of ratios in everyday life:

• Mechanics: spanners/wrenches are all marked with relevant ratios which correspond to the nuts they fit.
• Businesses and accountants: use ratios for forecasting and financial controls (expense ratio, turnover ratio, debt ratio, asset ratio, price ratio, earnings ratio etc.)
• Food: the correct diet has the right ratio of food groups (one of our five a day is a common ratio we are all familiar with.
• Education: ensuring the right ratio of students to teachers is key for effective learning. Class sizes in terms of the ratio of pupils to a teacher is a common ratio concern.
• Web Developers / SEO experts: these tech guys live and breathe ratios, from bounce rates to time on site, new visitors versus return visitors, ratios rule their lives.

When calculating equivalent ratios you must multiply or divide both numbers in the ratio. This keeps both numbers in direct relation to each other. So, a ratio of 2/3 has an equivalent ratio of 4/6: in this ratio calculation we simply multiplied both 2 and 3 by 2.
