About us

Why Calculating power analysis is important?

A power analysis can assist you to determine the size of sample you need to create to achieve accurate statistical outcomes. The purpose of power analysis and sample size calculation is to determine the sufficiency of power as well as to determine the appropriate sample size, so that utilizing too large (may waste money, resources and time) or too small (inaccurate result) may be avoided. Without power calculations, it would be challenging to assume the sample size

Ph.D. Assistance to calculate Power

Estimating statistical power and determining sample size would be a bit tricky and required skills and experience to run the same. At Ph.D. Assistance, we help you to calculate power and sample size your study.

The sample size determination at Ph.D. Assistance are conducted with the help of power analysis. It is an important factor to have certain information. This information is needed for both calculating sample size and statistical test that you plan to use for the sample size calculations. Apart from the statistical test, you need to know the appropriate effect to determine sample size.

When designing a quantitative study, the following questions usually come up

  • How many participants do I need in my research study sample
  • Which test and measure should I utilize for data analyses?
  • Will I have adequate power with the number of participants chosen?

Especially statistical power analysis approach permits the quantitative researcher to decide:

  • How many sizes of the sample are required to enable statistical judgment that is more reliable and accurate?
  • How appropriate is the selected statistical test to detect the effects of a given size based on circumference?

Ph.D. Sample size and Power Analysis features

Different types of Statistical power analysis offered at Ph.D. Assistance.

There are different types of power analysis:

  • Prior power analysis - This analysis is implemented before the study is conducted
  • Post-hoc power analysis –This analysis is executed after the study is conducted

  • Alpha (α) - Rejection of the correct null hypothesis [Probability of Type I Errors]
  • Beta (β) - Acceptance of a false null hypothesis [Probability of Type II Errors]
  • Effect size - Measure of the strength of the relationship between two variables

Apart from this factor, G*Power is the program that assists you to conduct a power analysis and select a suitable sample size. G*Power analytics tool performs high accuracy statistical power analysis for general statistical tests such as F-tests, T-tests, and Chi-Square analyses. Today, growing acceptances of the importance of the power analysis and sample size calculations is required in the proper design of a Quantitative study.
