Detailed explanation-1: -I would try to write the results as “In a preliminary study, we find that p < 0.10 is suggestive of a significant effect that warrants further study.", or something like that.
Detailed explanation-2: -The significance level usually is chosen in consideration of other factors that affect and are affected by it, like sample size, estimated size of the effect being tested, and consequences of making a mistake. Common significance levels are 0.10 (1 chance in 10), 0.05 (1 chance in 20), and 0.01 (1 chance in 100).
Detailed explanation-3: -If the p-value is less than 0.05, we reject the null hypothesis that there’s no difference between the means and conclude that a significant difference does exist. If the p-value is larger than 0.05, we cannot conclude that a significant difference exists.
