Q: When writing about a significance level, what kind of writing is best?
When writing about a significance level, which of the following is best?
1. levels of significance: 0.05
2. levels of significance: p≤0.05
3. levels of significance: 5%
The significance level is denoted by the Greek letter α and is used to indicate the likelihood of the null hypothesis being rejected. The probability of obtaining a specific result is denoted by the letter p (usually italicized). Most studies consider the level of significance to be 5% but this can vary. When p < α, the null hypothesis is assumed to be rejected.
To answer your question, the most common way of writing this is to say that the significance level is 0.05.
