I would be curious to see thestatistical significanceof the regression, using the relevant serial correlation corrected standard errors. Thestatistical significanceof the difference between the mean value of groups was tested by Student's t test for unpaired values. ...
Statistical significance is important when assessing the results of statistical analysis, but you also need to look at the actual statistic values involved and decide whether they are practically significant, with meaningful real-world implications. And while we do want to have sample sizes large enou...
Misinterpretations are both common and persistent, leading many to question whether significance tests should be used at all. While most take aim at the arbitrary declaration of p?P-values and significance tests are still widely used as if they give a measure of the size and importance of ...
significance. In this problem,T-tests have been conducted with a significance value,α=0.05.P-values have been calculated for each pair of algorithms.P-values less thanαrepresent that the difference of the means of the groups is statistically significant.Table 4lists theP-values for this ...
Conventionally, if the I p i -value is lower than the 0.05 significance level, we reject the null hypothesis and accept the alternative hypothesis. At the beginning of our research training, we learned about hypothesis testing, I p i -values, and statistical inference....
When diving into the world of statistical significance, one of the key decisions you'll make is whether to use a one-tailed or two-tailed test. The choice hinges on the nature of your hypothesis and what you aim to discover through your research. ...
It will also explain the types of errors and how to use P-values in decision-making. Read on for the nitty-gritty details about understanding and applying statistical significance measures so that you can make smarter business decisions. It won't take long before you can calculate and ...

P value and alpha values are compared to establish the statistical significance.If p value <= alpha we reject the null hypothesis and say that the data is statistically significant. otherwise we accept the null hypothesis.T-TestT-tests are used to determine if there is significant deference ...
In order to use p-values as a part of a decision process external factors part of the experimental design process need to be considered which includes deciding on the significance level (threshold), sample size and power (power analysis), and the expected effect size, among other things. If...
