Answer:
X is the quantity value
Explanation:
To calculate the variance follow these steps: Work out the Mean (the simple average of the numbers) Then for each number: subtract the Mean and square the result (the squared difference). Then work out the average of those squared differences. Then the standard deviation of X is the quantity. (derived using the properties of expected value). In other words, the standard deviation σ (sigma) is the square root of the variance of X; i.e., it is the square root of the average value of (X − μ)2.

The experimental error refers to the dissimilarity between a measurement and the true value or between the two measured values. Experimental error is determined by its accuracy and precision.
A variation in data, or error, basically signifies whatever results in the data to be imperfect, not the human mistakes. In order to correct this, there is a need to get familiar with the unavoidable sources of error and how they take place so that one can reduce their effect and get the best probable data.
As the procedure has asked you to do, you require a microscope in order to complete the task. The questions below the circles, can only be answered when you have observed the slides. We cannot simply solve this for you, this is an individual/partner task that requires you to find out yourself.
