The same,if you have accurate reading of measurement in graphical method you can precisely measure so there will be no error, in using analytical method you must have an exact & perfect calculation to have an perfect product.
.
The graphical method is suitable only if there are exactly 2 variables. If the no . of variables are 3, constructing a 3-D graph is quite difficult to interpret . If the no. of constraints are more, the graph becomes a mess.
Analytical range refers to the method/procedure used, It can include a non linear response. If you plot the analytical results versus the reference values you will have a linear curve. The linear range could be more precisely given by saying the linear instrument range
A scatter diagram will give a quick but rough extimate of the trend line - especially if there is a lot of variation about the trend. The least squares method will be more accurate.
The more accurate number - is 1.005 - as it is accurate to more decimal places than the other examples.
They are both the same but 2.5 is more accurate because the zeros after 2.5 have no values
The pycnometer method is more accurate than the hydrometer method because it uses an analytical balance.
The graphical method is often approximate but can be applied to any function. If done on a computer, the region surrounding the solution can be enlarged to obtain more accurate estimates. A numerical method will give an exact result is an analytical solution is possible. If not, the solution will depend on the numerical method used and, sometimes, the starting "guesstimate".
graphical method is applicable only for solving an LPP having two variables in its constraints , but if more than two variables are used, then it is not possible to use graphical method. In those cases, simplex method helps to solve such problem. In simple, in graphical method is used when the constraints contain two variables only. But simplex method can be used to solve constraints having more than two variables.
Parallelogram method is not that accurate because a mechanical tool such as protractor is used in constructing the angle of a vector or in other words it is only an illustration unlike in analytical method of adding vectors, mathematical computation is used which is more accurate than making an illustration to present vectors.
Analytical method development, in simple terms, is the process of proving that an analytical method is suitable for use to measure concentration of an active pharmaceutical ingredient in a dosage and will allow more simple methods to verify that it is a reliable measurement.
The graphical method is suitable only if there are exactly 2 variables. If the no . of variables are 3, constructing a 3-D graph is quite difficult to interpret . If the no. of constraints are more, the graph becomes a mess.
Which method of determining turn ratio is more accurate and why?
Hemoglobinometer
When you have 3 variables or more. In paper, we can only draw 2 dimensional shapes.
You will obtain a more accurate answer than is possible using graphical methods. It's faster and less work than using a table.
Dual Energy X-Ray Absorptiometry is the most accurate method of measuring body fat composition. This method is more commonly referred to as DEXA.Hydrostatic weighing
So they can get a more accurate answer
