Actually, it's the other way around...
If something is statistically significant, it may or may not be practically significant. Example: A new pill is proven to reduce the average time someone has the flu from 9 days to 8.85 days. Because it has been proven, it is statistically significant; however, a decrease in .15 days isn't practically significant.

What does statistical significance refer to?
Statistical significance refers to when a statistical assessment of observations reveals a pattern rather than random chance. In simpler terms it means when well observing or recording a set of data you recognize that somethings happens all or most of the time rather than by random.
Is statistical significance below or above 0.05?
If the outcome is below or equal to 0.05, then it is statistically significant; above is not.
To decide whether observed differences between samples reflect actual differences between?
statistical significance
How is a point-biserial correlation coefficient tested for statistical significance?
See Terrell, C. D. (1982). Significance tables for the biserial and point biserial. Educational and Psychological Testing, 42, 975-981.
0.02 level of significance what is the critical value?
The critical value for a 0.02 level of significance, denoted as α = 0.02, in a statistical test corresponds to the point on a distribution that separates the critical region (rejection region) from the non-critical region. To find the critical value, you would consult a statistical table or use a statistical calculator based on the specific test you are conducting (e.g., z-table, t-table, chi-square table). The critical value is chosen based on the desired level of significance, which represents the probability of rejecting the null hypothesis when it is actually true.

What is the difference between statistical significance versus practical significance?
Statistical significance means that you are sure that the statistic is reliable. It is very possible that whatever you conclusion or finding is, it may not be important or it not have any decision-making utility. For example, my diet program has a 1 oz weight loss per month and I can show that is statistically significant. Do you really want a diet like that? It is not practically significant
What are examples of practical significance?
Practical significance refers to the real-world relevance or importance of a finding, beyond mere statistical significance. For example, a new medication may show a statistically significant reduction in symptoms, but if the actual improvement is minimal and doesn't enhance quality of life, it may lack practical significance. Similarly, a study might find that a training program improves employee productivity by 1%, which, while statistically significant, may not be meaningful enough to justify its cost. Thus, practical significance helps determine if results can lead to actionable decisions or improvements in practice.
Why is statistical significance not necessarily of practical importance to a business decision?
Some data in statistics can affect numbers, which will skew the data. When this happens managers should make business decisions that ignore the stats.
What is the statistical Significance of three in religion?
It represents unity.
Definition of practical significance?
Practical significance in statistics is concern with whether the acquired research result is useful in the real world verus in theory which is not practical.
What is the difference between practical generalizability and statistical generalizability?
Statistical: must have random sampling, allows you to generalize to the population from which you randomly selected. Practical: do the results hold for similar individuals? allows you to generalize to similar individuals
F-test is less than 1?
There is no statistical significance in the result.
What does statistical significance refer to?

What is the difference between clinical significance and statistical significance?
look for a paper being published in "The Oncologist" later this year (2008)
What are the advantages and disadvantages of hypothesis testing studies?
Hypothesis testing studies offer the advantage of providing a structured framework for evaluating research questions, allowing researchers to draw conclusions based on statistical evidence. They can identify significant effects or relationships, contributing to scientific knowledge. However, disadvantages include the potential for misinterpretation of p-values, reliance on arbitrary thresholds for significance, and the risk of overlooking practical significance in favor of statistical significance. Additionally, hypothesis testing may encourage a narrow focus on confirmatory analysis rather than exploratory research.
What is a Alpha Value?
The level of significance; that is the probability that a statistical test will give a false positive error.
