Importance of statistics in analytical chemistry.?
i am a student of chemistry and have an assignment of statistical role in chemistry and i have no idea about please guide in this way?
Why is it necessary to learn statistics?
Statistics is an analytical tool that helps people make rational decisions. Almost everyone understands what an average value is, and while that is useful information in making comparisons (as in shopping) it doesn't tell the whole story. To know that two numbers are really different you need to know about the spread in the data and that is one of the key concepts in statistics.
How is statistics used in Analytical chemistry?
In Analytical chemistry and especially the analysis of elements the main purpose is to identify even very, very small traces of certain substances. So, now, if you want to check i.e. a tree or its leafs... concidering environmental pollution or whatever... you choose your zone, where you take the samples, the amount of every sample (equal everywhere would be best - recommended), etc. At the end, you got a bunch of numbers after having evaluated the i.e. leafs... but, is your result representing the reality... what's about your method for the measurement, any errors? Statistics in Analytical Chemistry helps to represent the results. It gives a possibility to indicate how precise this measurements are (with a range of errors). All this together allows a statement about the real situation... even if you only took a few hundred samples...
What does analytical factors mean?
Analytical factors are the individual facts and pieces of data you use when analysing a specific thing.
Types of statistics?
There are two types of statistics. One is called descriptive statistics and the other is inferential statistics. Descriptive statistics is when you use numbers. Inferential statistics is when you draw conclusions or make predictions.
