Type 1 Error:In hypothesis testing, there are two types of error, Type 1 error, and Type 2 error. The type one error is denoted by the {eq}\alpha {/eq} and type 2 error is denoted by the {eq}\beta. {/eq} Type 1 error is more serious that type 2 error....
A fire alarm provides a good analogy for the types of hypothesis testing errors. Preferably, the alarm rings when there is a fire and does not ring in the absence of a fire. However, if the alarm rings when there is no fire, it is a false positive, or a Type I error in statistical...
Types of errors When we decide whether to reject a restriction or not to reject it, we can incur in two types of errors: reject the restriction when the restriction is true; this is called an error of the first kind or aType I error; do not reject the restriction when the restriction ...
In hypothesis testing we have to worry about two kinds of errors. A Type I error, also called a false positive, is when we accept a hypothesis that is actually false; that is, we consider an effect significant when it was actually due to chance. A Type II error, also called a false...
This result depends on the level of significance, the sample statistic, sample size, and whether it is a one- or two-sided alternative hypothesis.Types of ErrorsWhen testing, we arrive at a conclusion of rejecting the null hypothesis or failing to reject the null hypothesis. Such conclusions ...
If the alterna-tive hypothesis in a statistical testing problem states that the null hypothesis is wrong, then an error of the third kind cannot occur. This error can only be defined in more-decision-problems, i.e. prob-lems where we have to decide for one of more than two possibilities...

Hypothesis testing allows a mathematical model to validate a claim or idea with a certain confidence level. However, like the majority of statistical tools and models, it is bound by a few limitations. The use of this model for making financial decisions should be considered with a critical eye...
