  • Effect size - Wikipedia

    This means that for a given effect size, the significance level increases with the sample size. Unlike the t-test statistic, the effect size aims to estimate a population parameter and is not affected by the sample size. Cohen's d. Cohen's d is defined as the difference between two means divided by a standard deviation for the data, i.e.

  • Particle-size distribution - Wikipedia

    The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.

  • Normal Distribution

    Sample size has a significant effect on sample distribution. It is often observed that small sample size results in non-normal distribution. This is a result of inadequate estimation of the dispersion of the data, and the frequency distribution does not result in a normal curve. ...

  • Statistical Significance, Sample Size and Expected Effects

    This is to be expected because larger the sample size, the more accurately it is expected to mirror the behavior of the whole group. Therefore if you want to reject your null hypothesis, then you should make sure your sample size is at least equal to the sample size needed for the statistical significance chosen and expected effects.

  • Statistical significance - Wikipedia

    Statistical significance plays a pivotal role in statistical hypothesis testing. It is used to determine whether the null hypothesis should be rejected or retained. The null hypothesis is the default assumption that nothing happened or changed. For the null hypothesis to be rejected, an observed result has to be statistically significant, i.e. the observed p-value is less than the pre ...

  • Using Effect Size—or Why the P Value Is Not Enough

    The level of significance by itself does not predict effect size. Unlike significance tests, effect size is independent of sample size. Statistical significance, on the other hand, depends upon both sample size and effect size. For this reason, P values are considered to be confounded because of their dependence on sample size.
