What does it mean for the finding of a statistical analysis of data to be statistically significant?
Data is statistically significant if the p (probability) value is below a certain level (ex: 5% or 1%). The p value describes how often one would receive the results they got if left to chance alone. The lower the p value, the less likely it is that your results were due to chance and is stronger evidence against the null hypothesis. Also important to keep in mind is that just because something is statistically significant does not mean it is practically significant.
Is 0.045 Statistically Significant?
Whether 0.045 is statistically significant depends on the context, specifically the predetermined significance level (alpha) for the analysis. Commonly, a p-value of 0.05 is used as a threshold, meaning that a p-value of 0.045 would be considered statistically significant, indicating strong evidence against the null hypothesis. However, it's essential to consider the study design, sample size, and practical significance when interpreting this result.
What does the p value of 0.07 mean?
A p-value of 0.07 indicates that there is a 7% probability of observing the data, or something more extreme, if the null hypothesis is true. This value suggests that the evidence against the null hypothesis is relatively weak, as it is typically considered not statistically significant at the common alpha level of 0.05. However, it may still indicate a trend worth further investigation or consideration, particularly in exploratory studies.
Is .001 in statics from the Independent Samples t Test analysis a significant finding?
In the context of an Independent Samples t-Test, a p-value of .001 indicates a statistically significant finding, meaning there is strong evidence to reject the null hypothesis. This suggests that the difference in means between the two groups being compared is unlikely to have occurred by chance. Typically, a p-value below .05 is considered significant, so .001 is well below this threshold.
What is p0.0001?
The notation p0.0001 typically refers to a p-value in statistical hypothesis testing, indicating the probability of observing results as extreme as those in the data, assuming the null hypothesis is true. A p-value of 0.0001 suggests strong evidence against the null hypothesis, as it indicates that there is only a 0.01% chance that the observed data would occur under the null hypothesis. In many scientific fields, a p-value below 0.05 is considered statistically significant, making p0.0001 highly significant.

Is 0.001 statistically significant?
Statistical significance is determined by comparing a p-value to a predetermined significance level, often set at 0.05. A p-value of 0.001 indicates a result that is highly statistically significant, as it suggests a less than 0.1% probability that the observed effect is due to chance. Thus, if this p-value is derived from a relevant analysis, it would typically be considered statistically significant.
Is 0.045 Statistically Significant?
Whether 0.045 is statistically significant depends on the context, specifically the predetermined significance level (alpha) for the analysis. Commonly, a p-value of 0.05 is used as a threshold, meaning that a p-value of 0.045 would be considered statistically significant, indicating strong evidence against the null hypothesis. However, it's essential to consider the study design, sample size, and practical significance when interpreting this result.
Which of these is closest to what you mean to statistically significant?
Statistically significant is the term used to define when two data are distinct enough in value as to be considered different values. To determine whether two data are close enough in value or distinct enough in value to be considered the same or different, usually you have to do a p-test or a t-test, depending on the type of data that you are looking at. Then confer with the corresponding chart for the test that you did to see whether or not the data is statistically significant.
What is a researcher who engages in p-hacking trying to achieve?
A researcher who engages in p-hacking is trying to manipulate or cherry-pick data in order to find statistically significant results, even if the results are not truly meaningful or valid.
Is 0.099 significant in a p-value of 0.05?
Yes, a p-value of 0.099 is greater than the significance level of 0.05. This indicates that the result is not statistically significant, meaning there is insufficient evidence to reject the null hypothesis at that level of significance. Therefore, the finding may not be considered strong enough to draw definitive conclusions.
What is a significantly significant p value?
A significantly significant p-value typically refers to a p-value that is less than a predetermined threshold, commonly set at 0.05. This indicates that the observed results are unlikely to have occurred by random chance alone, suggesting that there is a statistically significant effect or relationship in the data. In scientific research, a p-value below this threshold often leads to the rejection of the null hypothesis. However, it's important to consider the context and other factors, such as effect size and study design, when interpreting p-values.

What does the p value of 0.07 mean?
A p-value of 0.07 indicates that there is a 7% probability of observing the data, or something more extreme, if the null hypothesis is true. This value suggests that the evidence against the null hypothesis is relatively weak, as it is typically considered not statistically significant at the common alpha level of 0.05. However, it may still indicate a trend worth further investigation or consideration, particularly in exploratory studies.
How do you tell if a wilcoxon test is significant?
To determine if a Wilcoxon test is significant, you compare the p-value obtained from the test to your chosen significance level (commonly 0.05). If the p-value is less than or equal to this threshold, you reject the null hypothesis, indicating that there is a statistically significant difference between the groups being compared. Additionally, examine the test statistic and confidence intervals for further insight into the effect size and direction of the difference.
How do you know when there is a significant difference in statistics?
In statistics, a significant difference is typically determined through hypothesis testing. This involves comparing the observed data with what would be expected by chance alone. If the difference between the observed data and what is expected by chance is large enough, it is considered statistically significant. This is typically determined by calculating a p-value, with a lower p-value indicating a higher level of statistical significance.
