Usually less than 0.05; sometimes less than 0.01 is used for special instances.
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.
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.
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.
Illusory correlation refers to the perception of a relationship between two variables that does not actually exist or is weaker than perceived. This phenomenon is not statistically significant, as it arises from cognitive biases rather than true statistical relationships. Statistical significance is determined through rigorous analysis of data, typically using p-values or confidence intervals, which would not support an illusory correlation. Therefore, while illusory correlations can influence beliefs and perceptions, they lack a solid statistical foundation.

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.
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.

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.

P-value is short for "Probability Value." It is a measure of statistical significance whereas the p-value is the probability of obtaining a test statistic at least as extreme as the one that was actually observed, assuming that the null hypothesis is true. The lower the p-value, the less likely the result is if the null hypothesis is true, and consequently the more "significant" the result is.
A figure is considered significant if it represents a statistically meaningful result, typically determined by comparing it to a threshold value (e.g., p < 0.05). Significance indicates that the observed difference or relationship between variables is unlikely to have occurred by chance. Conducting statistical tests such as t-tests or ANOVAs can help determine the significance of a figure.
A P-value of 0.5 means that the probability of the difference having happened by chance is 0.5 in 1, or 50:50. P=0.05 means that the probability of the difference having happened by chance is 0.05 in 1. i.e. 1 in 20. it is the figures frequently quoted as 'statistically significant', i.e. unlikely to have happened by chance and therefore important. Remember the lower the P value, the less likely it is that the difference happened by chance and so higher the significance of the finding. If P is low Null must Go! So a P-value 0.01 is often considered to be 'highly significant'. it means that the difference will only have happened by chance 1 in 100 times. If P-value 0.001 means the difference will have happened by chance 1 in 1000 times, even less likely, but still just possible. considered 'very significant'
