In statistics:

type 1 error is when you reject the null hypothesis but it is actually true.

Type 2 is when you fail to reject the null hypothesis but it is actually false.

### Relationship between type 1 error and type 2 error?

In statistics, there are two types of errors for hypothesis tests: Type 1 error and Type 2 error. Type 1 error is when the null hypothesis is rejected, but actually true. It is often called alpha. An example of Type 1 error would be a "false positive" for a disease. Type 2 error is when the null hypothesis is not rejected, but actually false. It is often called beta. An example of Type 2 error would be a "false negative" for a disease. Type 1 error and Type 2 error have an inverse relationship. The larger the Type 1 error is, the smaller the Type 2 error is. The smaller the Type 2 error is, the larger the Type 2 error is. Type 1 error and Type 2 error both can be reduced if the sample size is increased.

### Which error is more serious a Type 1 or Type 2 error?

type1 error is more dangerous

### What is the difference between type 1 error and type 2 error?

diabetes are two type 1insulin dependent diabetes 2 non insulin dependent diabetes

### If the probability of type 1 error is reduced the probability of type 2 error is also reduced?

No....the two are mirror images of each other. Reducing type I would increase type II

### When performing a study what is a type 2 error?

A type 2 error is when you accept your null hypothesis when in fact the alternative is true. A type 2 error is also known as a false negative.

### Does taking insulin turn type 2 into type 1?

I believe that Type 1 is an autoimmune disease and Type 2 is not, so with Type 1 auto antibodies are present and with Type 2 they are not. Therefore, I do not believe that taking insulin can turn Type 2 into Type 1. The cause of Type 1 is still unknown.

### What is along and digital control system?

A: The last time that i kept up with types of systems there were only three what is along?. Well anyhow type-0 system is one that requires a constant error signal to operate type-1 a constant rate of change of the controlled variable requires a constant error signal under steady state condition. type 1 is usually referred as servomechanism system. type-2 a constant acceleration of the control variable requires a constant error under steady state condition. type-2 sometimes is referred to as zero velocity error system
