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.
The power of a test is 1 minus the probability of a Type II error.
Accept lower p-values (meaning lower in magnitude; values tending toward zero).--And don't forget that by reducing the probability of getting a type I error, you increase the probability of getting a type II error (inverse relationship).
In some cases a choice of tests may be available; some tests are more powerful than others.Use a larger sample.There is a trade-off between Type I and Type II errors so you can always reduce the Type I error by allowing the Type II error to increase.
This will reduce the type 1 error. Since type 1 error is rejecting the null hypothesis when it is true, decreasing alpha (or p value) decreases the risk of rejecting the null hypothesis.
No....the two are mirror images of each other. Reducing type I would increase type II
The power of a test is 1 minus the probability of a Type II error.
genetic relationship between the lupus and type 1 diabetes is important because immune system have in relation with lymphatic system
diabetes are two type 1insulin dependent diabetes 2 non insulin dependent diabetes

1 inches = 2.54 centimeters
type1 error is more dangerous
Dismental the calculator and press type 1 error there you got it( for any calculator

It depends on the slope ofthe linear graph. if y=x then the relationship is 1:1 if y=3x then the relationship is 3:1 if y=2/7x then the relationship is 2:7
This will reduce the type 1 error. Since type 1 error is rejecting the null hypothesis when it is true, decreasing alpha (or p value) decreases the risk of rejecting the null hypothesis.
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.

Type I error happens when a difference is being observed when in truth, there is none or there is no statistically significant difference. This error is also known as false positive.
