How did you find the range?
Summary: The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
What is mean median and range?
– Median:The number in the MIDDLE when they are IN ORDER! – Mean- The AVERAGE OF ALL NUMBERS: You add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS! – Range – THE BIGGEST minus the Smallest! There you go guys! Reply.
What is range and mode?
The mode is the number that occurred the most often. The range is the difference between the highest and lowest values.
Why is the average called the mean?
A statistician or mathematician would use the terms mean and average to refer to the sum of all values divided by the total number of values, what you have called the average. This especially true if you have a list of numbers. There are times however that this is called the mean.
What is average mean in math?
In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.
What is an average in statistics?
In statistics, an average is defined as the number that measures the central tendency of a given set of numbers. There are a number of different averages including but not limited to: mean, median, mode and range.
What is average explain with example?
A calculated “central” value of a set of numbers. To calculate it: add up all the numbers, then divide by how many numbers there are. Example: what is the average of 2, 7 and 9? Add the numbers: 2 + 7 + 9 = 18. Divide by how many numbers (i.e. we added 3 numbers): 18 ÷ 3 = 6.
What is average and its types?
There are three main types of average: mean, median and mode. The mean is the most commonly used average. To get the mean value, you add up all the values and divide this total by the number of values.
What is use average?
Averages are used to represent a large set of numbers with a single number. It is a representation of all the numbers available in the data set. The average is calculated by adding all the data values and dividing it by the number of the data point. Average has numerous applications in our day to day life. …
Where is average used?
1) Average is used for comparing height of the students in two different classes of a school. 2) Literacy rate of the country is calculated by average. 3) It is used to compare the marks of the students obtained in the class.
Why do we calculate mean?
The mean is essentially a model of your data set. It is the value that is most common. That is, it is the value that produces the lowest amount of error from all other values in the data set. An important property of the mean is that it includes every value in your data set as part of the calculation.
What is average in simple words?
An average is the “normal” number of a group of numbers made by mixing the group of numbers. In math, an average is called a mean. It can be found by adding the numbers, then dividing the answer by the number of numbers there were.
What is the average weight for a 11 year old?

What is average power?
Average power is defined as the ratio of total work done by the body to the total time taken by the body.
How do you calculate the power rating?
Multiply the value for the current by the value for the voltage to determine the power rating. This quantity will be resolved in units of wattage (watts).
What is the equation for efficiency?
Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output (“product”) produced per the amount C (“cost”) of resources consumed.
What is the minimum power?
This theory predicts that the most likely coalition to form in a group will be one that wins but comprises the individuals with the smallest amounts of power consistent with this outcome. …
How do I find out my current power supply?
Ohms Law and Power
- To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)
- To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)
- To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)
- To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)
