# Statistical Significance Calculator

Enter the number of clicks and conversions (or conversion rate) and get the intervals in which a conversion can lie with a probability of 70%, 80%, 90%, 95% and 99%

The diagram shows what the conversion can be with a probability of 95% (confidence interval).

A probability of 95% (`p < 0.05' }}`

) is taken as the generally accepted level of statistical significance.

**0%**-

**0%**

±0%

### Here are the results:

- Probably
**99%**conversion is between**0%**and**0%**. Deviation**±0%** - Probably
**95%**conversion is between**0%**and**0%**. Deviation**±0%** - Probably
**90%**conversion is between**0%**and**0%**. Deviation**±0%** - Probably
**80%**conversion is between**0%**and**0%**. Deviation**±0%** - Probably
**70%**conversion is between**0%**and**0%**. Deviation**±0%**

Instead of clicks and conversions, you can use impressions and clicks respectively to count CTR values instead of conversions.

Actually, it's not really a statistical significance calculator,
`70%.. 99% = 1 - p`

where p — significance level, i.e.
it is already set by us.

The mathematical model uses some assumptions, so
values - not the ultimate truth. Keep in mind :)
