Type I and Type II Error

 In this we are going to explain about Type I and Type II error like false positive and false negative.


False positive

False - Outcome whether is was true or False

Positive - It's action or indication by device or process. 

False Positive : Device say it's there which is in actual false mean in actual it was not there . False alarm.

False negative : kind of device is not working. negative means device say it's not there. Which is false statement. so in actual it's there but device not able to detect. Broken Alarm. 

Example: There is a Alien detector machine. Which indicate if there is any alien nearby. 

False positive : positive means detector say there is an Alien which is false. In actual there is no Alien. This situation is fine as we might check manually for Alien or get alert. Even though it's false alarm not getting any harm. 

False Negative : Negative means detector say there is no Alien which is false. In actual there is an Alien. This is not good because it's not able to detect Alien. Kind of device is not working. 

Type II Error is more dangerous than Type I.
