The average is used to provide a central value that represents different values to make an analysis or a comparation. The attached image shows a plot comparing the averages of plants growth.
<h3>What is an average?</h3>
In simple words, the average is the addition of a group of values divided by n, which is the total number of values considered. It is also known as media.
It is used to provide a single central value that represents several different values.
Group of values: X₁, X₂, X₃, X₄, X₅
n = 5
Average = (X₁ + X₂ + X₃ + X₄ + X₅) / 5
In the exposed example,
1) In the attached files you will find the image of the table.
According to this image, there is no errors. You should compare this table with yours and analyze if there is any difference.
2) Average of the heights of the plants treated with pure water
Group of values: 10, 12, 8, 9
n = 4
Average = (10 + 12 + 8 + 9) / 4 = 39/4 = 9.75
3) You will find the graph in the attached files.
In these graphs you will find
- a combined graph in which it is detailed the growth of each plant together with the average growth per treatment.
- another bar graph only representing the averages of heights of plants.
