Avoid Common Errors In Statistics







Statistics are as common even in casual conversation such as talking about the weather. You will often hear percentage rates and ratios as a means of comparing information. Many people believe that most statistics are made up, and students taking statistics courses likely see how accurate that belief is. Unfortunately, statistics students make common errors as well, which may lead to those inaccurate statistics found in small talk. The steps below will help you to avoid the common mistakes you may make while studying statistics.








Instructions


1. Know that just because specific results occur from the tests you perform, there might not be a causal relationship between the elements you test. It is important to take all factors that may affect your test results into consideration when formulating your statistics.


2. Watch the language you use to explain your statistics. Clearly state what and how you are comparing factors. The more details you provide, the better individuals will understand your results.


3. Be certain of the statistical significance of the results you reach. The sample size you use and possible random effects of your tests will determine whether the statistics you reach are truly significant.


4. State clearly the base point of your tests when using graphs to explain your statistical results.


5. Perform a reasonable number of tests to examine your statistics. Too few or too many tests can result in an inaccurate significance for your findings.


6. Keep estimations of unknown values in the parameters of the known values, rather than estimating outside the known limitations.
