Theoretical Yield :
The maximum amount of product that can, according to chemical reactions, be obtained from a known amount of reactants. Cannot reach theoretical yield in reality, instead find percent yield.
More about Theoretical Yield
Percent Yield( = (Actual yield - Theoretical Yield / Theoretical yield) ×100)

Dimensional Analysis :
A method for solving conversion type problems
a. Understand the question
b. Understand what is given and units involved
c. Figure out which conversion factors you need
d. Decide how to use the factors
e. Keep the units as a check for your work

Accuracy : The measure of agreement between your average of measurements and the correct value
Precision : The closeness of agreement among repeated measurements.

Mean
Standard Deviation :
Indicates confidence limits for analyzed data, which gives you an idea of how widely spread out your data is and you can recognize outlying values.
Calculations:
  1. Determine the mean, m.
  2. Subtract the mean from each measured data item, d.
  3. Square each difference, d².
  4. Find the average of the squared terms in step 3 by dividing by (n-1), n is the number of measurements taken.
  5. Calculate the square root of the average found in step 4.
