The R diff function subtracted the first value from the second, the second value from the third, the third value from the fourth, and the fourth value from the fifth. In other words: diff returned the first lag to the RStudio console.

To get from −8 to the answer you really want, just take the absolute value! That is, to find the distance between any two real numbers: subtract them in any order. take the absolute value of the result.

A simple way to calculate the distance between numbers on a number line is to count every number between them. A faster way is to find the distance by taking the absolute value of the difference of those numbers. For example, the absolute values of 4 and -4, or |4| and |-4|, are both 4.

Find the absolute difference between two numbers: |20 - 30| = |-10| = 10. Find the average of those two numbers: (20 + 30) / 2 = 50 / 2 = 25. Divide the difference by the average: 10 / 25 = 0.4. Express it as percentages: 0.4 * 100 = 40%

Percentage Difference Formula: Percentage difference equals the absolute value of the change in value, divided by the average of the 2 numbers, all multiplied by 100.

To test for the significance of a difference between two numbers, assume they are Poisson counts. Input two observed counts in the top two boxes. All the other boxes should have the value zero ('0'), and you will get a P value.

First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100.

First: work out the difference (decrease) between the two numbers you are comparing. Then: divide the decrease by the original number and multiply the answer by 100. If your answer is a negative number, then this is a percentage increase.

To calculate the percentage increase, work out the difference (increase) between the two numbers you are comparing. Then divide the increase by the original number and multiply the answer by 100. If your answer is a negative number, then this is a percentage decrease.
