“Positive difference” means that when you subtract a – b you can get +5 or -5. (That’s also what the absolute value indicates.) Solve for a in both cases: a – b = 5, so a = b + 5; and a – b = -5, so a = b – 5.

What is the meaning of difference in math?
The result of subtracting one number from another. How much one number differs from another. Example: The difference between 8 and 3 is 5.
What is the difference between positive and negative numbers?
A positive number is a number greater than zero. It can be written with or without a + symbol in front of it. A gain in something is written with a positive number. A negative number is a number that is less than zero.
How do you solve positive difference?
Divide both sides by 4. The difference between two numbers is the result of subtracting one from the other. It is usual to subtract the smaller number from the larger. This gives a positive difference.
What is the positive difference between two numbers?
Positive difference:This is when we subtract the smaller number from the bigger number. Negative difference:We get this by subtracting the bigger number from the smaller number.
What is range median and mode?
The median is the middle. You add and divide for the mean. The mode is the one that appears the most. And the range is the difference in between.
What is median of numbers?
The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. 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.
How do you find the median of a big set of numbers?
The median is 72.5. Tip: For large data sets, divide the number of items by 2, then subtract 1 to find the number that should be above and the number that should be below. For example, 100/2 = 50. 50 – 1 = 49.
What is the median of 11?
There are 7 numbers in the set, and they are arranged in ascending order. The middle number (the 4 th one in the list) is 11 . So, the median is 11 .
How do you find the median in Class 10 statistics?
Median is a measure of central tendency which gives the value of the middle-most observation in the data. In case of ungrouped data, we first arrange the data values of the observations in ascending order. Then, if n is odd, the median is the (n+1)/2 th observation.
How do you find the median less than type?
During a less than type ogive for the given data. Hence obtain the median weight from the graph – and verify the result by using the formula. Locatae 17.5 on the y-axis. From this point, draw a line parallel to the x-axis cutting the curve at a point.
