Can A Study Be Clinically Significant But Not Statistically Significant? A study outcome can be statistically significant, but not be clinically significant, and vice‐versa. Unfortunately, clinical significance is not well defined or understood, and many research consumers mistakenly relate statistically significant outcomes with clinical relevance. How do you determine if a study is clinically significant?
Why Would A Study Be Considered Invalid? “Findings can be said to be internally invalid because they may have been affected by factors other than those thought to have caused them, or because the interpretation of the data by the researcher is not clearly supportable” (Seliger & Shohamy 1989, 95). What can cause research to
When Should I Use Bonferroni Correction? The Bonferroni correction is appropriate when a single false positive in a set of tests would be a problem. It is mainly useful when there are a fairly small number of multiple comparisons and you’re looking for one or two that might be significant. Why do we use the
How Does Sample Size Affect P Values? The p-values is affected by the sample size. Larger the sample size, smaller is the p-values. … Increasing the sample size will tend to result in a smaller P-value only if the null hypothesis is false. What does significance level depend on? A significance level is influenced by
How Do You Report Non-significant Results In APA? When reporting non-significant results, the p-value is generally reported as the a posteriori probability of the test-statistic. For example: t(28) = 1.10, SEM = 28.95, p = . 268. How do you report non-significant results? A more appropriate way to report non-significant results is to report the
How Do You Explain The Significance Of Something? Significance means having the quality of being “significant” — meaningful, important. It also refers to the meaning of something. A certain date might have significance because it’s your birthday or the anniversary of Princess Di’s wedding. Significance starts with the word sign for a reason. How do
How Do You Know If Research Is Statistically Significant? A study is statistically significant if the p-value is less than the pre-specified alpha. Stated succinctly: A p-value less than alpha is a statistically significant result. A p-value greater than or equal to alpha is not a statistically significant result. How do you know if evidence
How Do You Justify Sample Size? In this overview article six approaches are discussed to justify the sample size in a quantitative empirical study: 1) collecting data from (an)almost) the entire population, 2) choosing a sample size based on resource constraints, 3) performing an a-priori power analysis, 4) planning for a desired accuracy, 5) using
How Do You Interpret Statistical Results? Step 1: Describe the size of your sample. Step 2: Describe the center of your data. Step 3: Describe the spread of your data. Step 4: Assess the shape and spread of your data distribution. Compare data from different groups. How do you analyze statistical results? Summarize the data.
How Do You Explain Statistical Significance? Statistical significance refers to the claim that a result from data generated by testing or experimentation is not likely to occur randomly or by chance but is instead likely to be attributable to a specific cause. … Simply stated, if a p-value is small then the result is considered
