chi-square test statistic Look up the critical chi-square statistic value for p = 0.05 (95% confidence level) with 1 degree of freedom 3.84 . Is it significant? • Test value > table value then REJECT H 0 • 146.67 > 3.84 We reject H 0 ‘the proportion of Firsts is the same for males and females’ Instead the H 1 is true that ‘the proportion of firsts is different for males and... This means that the probability value is 0.62, a value very much higher than the conventional significance level of 0.05. This result, therefore, does not give even a hint that the null hypothesis is false. However, we know (but Experimenter Jones does not) that π = 0.51 and not 0.50 and therefore that the null hypothesis is false. So, if Experimenter Jones had concluded that the null

If the study's p-value was 2% (<5%), it would have a statistically significant result. The p-value indicates there is only a 2% chance that the connection between foot size and gender was the...
If the p-value is under .01, results are considered statistically significant and if it's below .005 they are considered highly statistically significant. But how does this help us understand the meaning of statistical significance in a particular study?

To go beyond the naive and misleading practice in the quotation, you need to learn more about multiple regression. To see what can be learned in this regard, consider.

How To Know If Your P Value Is Significant

If your data met the assumption of homogeneity of variances, use Tukey's honestly significant difference (HSD) post hoc test. Note that if you use SPSS Statistics, Tukey's HSD test is simply referred to as "Tukey" in the post hoc multiple comparisons dialogue box). If your data did not meet the homogeneity of variances assumption, you should consider running the Games Howell post hoc test.

  • Answer. As the p-value is much less than 0.05, we reject the null hypothesis that β = 0. Hence there is a significant relationship between the variables in the linear regression model of the data set faithful.

  • Whenever we perform a significance test, it involves comparing a test value that we have calculated to some critical value for the statistic. It doesn't matter what type of statistic we are calculating (e.g., a t-statistic, a chi-square statistic, an F-statistic, etc.), the procedure to test for significance is the same.
  • To evaluate whether the p-value is significant, the common approach is to compare it against the traditional thresholds of alpha such as 0.05 or 0.001 etc. If the p-value is less than the chosen
