Power Analysis:
Factors that Matter

We take various factors into consideration when designing and conducting a power analysis for your study. Our team of experts ensures that your study has the necessary sample size, appropriate significance level and well-designed sampling method to achieve optimal power for your research.

Mean difference

The Mean difference refers to the magnitude of the difference or relationship being studied. A larger mean difference will increase the power of a study or experiment.

Variance

Variance refers to the spread of the data and how much it deviates from the mean. A lower variance will increase the power of a study or experiment.

Sample size

Sample size is the number of observations or participants in a study or experiment. A larger sample size will increase the power of a study or experiment.

Significance level

Significance level is the probability of detecting an effect when there is no effect. A lower significance level will increase the power of a study or experiment.

Sampling method

Sampling method refers to the way in which the observations or participants are selected for a study or experiment. A well-designed sampling method will increase the power of a study or experiment by ensuring that the sample is representative of the population being studied.

The Language of Power Analysis

Statistical power is a crucial aspect of any research study as it determines the ability of the study to detect a meaningful effect. The power analysis estimates one of these parameters when the values for the remaining three are known.This is useful in designing experiments to have better power and more statistically significant results. The parameters are as follows:

Effect Size
