Expert Answer

If you're given a set of data, find the smallest number, then the largest number. Subtract them from each other to get the range.

Question

How do I calculate mean, median and mode?

Community Answer

For mean, add all numbers up and divide them by how many numbers there are. For median, place all numbers in ascending order then find the middle number. For mode, find the most commonly-occurring number.

Question

How can I find the range with negative and positive numbers?

Community Answer

You know that if a negative number is higher, it is less (eg -4 < -2), so the negative with the "highest" number would be the lowest part, and you would then take the highest positive number, and then subtract the lower part from the higher. Eg: Your numbers are -9, -4, 0, 3, and 7. Well, you take the negative with the "highest" positive number, ie., -9, and then the highest positive number, 7. Subtract 7 - (-9), and you get 16.

Question

Why do we measure the range?

Donagan

Top Answerer

It gives us an overview of a set of data, an idea of how much "space" is contained within those data points.

Question

What if I have multiple low numbers and a multiple like 2, 2, 4, 5, 6, 14,14?

Community Answer

Repeats don't matter. You still have a minimum (2) and a maximum (14) and the range is the difference between them, 14 - 2 = 12.

Question

How do I turn decimals into a fraction?

Donagan

Top Answerer

Use the numbers in the decimal as the numerator, and choose a multiple of ten as the denominator. For example, if the decimal is .35, the numerator would be 35, and the denominator would be 100. For the decimal .842, the numerator would be 842, and the denominator would be 1,000. In each case you would reduce the fraction if possible. If the decimal were 2.25, the numerator would be 25, the denominator would be 100, and the mixed number would be 2 25/100, or 2¼.

Question

Can 0 be used as a number when working out the range?

Donagan

Top Answerer

Yes. Even though zero seems to have no value, it actually has a relative value and its own place on a number line. Therefore, it takes up space in a data set and must be considered when calculating range.

What is the range for measurement 200 +/- 3%?

Donagan

3% of 200 is 6. 200 + 3% = 200 + 6 = 206. 200 - 3% = 200 - 6 = 194. 206 - 194 = 12 (the range).

Question

How do you calculate mean?

Community Answer

Calculate the mean (or average) of a set of numbers by adding all the numbers together and then dividing that sum by the number of numbers in the set. For example, the mean of the numbers 1, 2, 3, 4 and 5 is (1 + 2 + 3 + 4 + 5) / 5 = 15/5 = 3. (The mean does not have to be a whole number.)

Question

How do you find the range when negative numbers are involved? For example: 241, -86, -42, -33, -46, -18, - 6, -2, -1, 3, 6, 9, 14, 26, 308.

Community Answer

It's the same process: subtract the lowest number from the highest number. In your example, it's 308 - (-86) = 308 + 86 = 394. That's the range. (When subtracting a negative number, change it to a positive number and add it.)

Question

How do you calculate median?

Community Answer

Arrange the numbers in either ascending or descending order. Then find the middle number. For example, if the numbers are 2, 3, 4, 5, 6, 7 and 8, the middle number is 5. That's the median. If there is an even number of numbers, there will be two middle numbers, in which case you take the average of those two. For example, if the numbers are 2, 3, 4, 5, 6, 7, 8 and 9, there are two middle numbers, 5 and 6. The average of those two numbers is (5 + 6) / 2 = 5½. That's the median.
