Simplifying Sample Size Calculation with Thesis PhD:
Would you move forward with your study if there was only a 25% chance of achieving a statistically significant result? Or would you prefer to know the minimum sample size required to detect a meaningful effect beforehand?
Then you’ve reached the right place
Why is Calculating Sample Size Important?
Conducting an accurate statistical power analysis is crucial in quantitative studies, as it determines the appropriate sample size needed for reliable and accurate results in statistical tests. Our team of statisticians calculates power and sample size based on factors such as effect size, population size, the alpha significance criterion (α), and statistical power or the chosen beta (β).

Importance of Calculating Sample Size:
Calculating the sample size is crucial in statistical research as it determines the amount of data needed to make accurate decisions. By performing sample size calculations, you can establish how large your sample needs to be to achieve reliable statistical outcomes. The primary goal of power analysis and sample size calculation is to ensure you have enough power for your study, thereby avoiding the pitfalls of using a sample size that is too large (wasting money, resources, and time) or too small (yielding inaccurate results). Without these calculations, there is no guarantee that your proposed sample size is appropriate.
For example, when comparing two target populations, if the sample size is less than 30, a T-test is typically used. Conversely, if the sample size exceeds 30, a Z-test is employed. Generally, for smaller target populations, a larger sample size is needed, whereas for larger target populations, a smaller sample size suffices. Additionally, sample size calculations vary depending on the desired margins of error.
Sample Size Calculation for Your Ph.D. Research – The One-Stop Solution for All Your Academic Research Needs:
At Thesis PhD, our expert statisticians specialize in calculating sample sizes using various statistical techniques and formulas to ensure accuracy. Sample size calculation methods can vary significantly depending on the chosen technique.
Our Ph.D. methodology experts consider several key criteria when determining the appropriate sample size for your study:
- Level of Precision: Ensuring the results are as accurate as possible.
- Level of Confidence or Risk: Establishing the probability that the results reflect the true population parameters.
- Degree of Variability in the Attributes Being Measured (Prevalence): Accounting for the diversity within the population.
- External Validity involves ensuring that the outcomes of a study can be applied or generalized to a broader population.
By meticulously evaluating these factors, we ensure that your research is based on an optimal sample size, enhancing the reliability and validity of your findings.

Ph.D. Sample Size and Power Analysis Options:
Different types of Statistical power analysis offered at Ph.D. Assistance.
There are different types of power analysis:
- Â Prior Power Analysis: Conducted before the study begins.
- Â Post-hoc Power Analysis: Carried out after the study concludes.
In power analysis, key factors such as sample size, alpha (α), beta (β), and effect size are calculated:
-  Alpha (α): Probability of rejecting the correct null hypothesis (Type I Errors).
-  Beta (β): Probability of accepting a false null hypothesis (Type II Errors).
- Â Effect Size: Indicates the strength of the relationship between variables.
Additionally, we consider:
 Sampling Error: This indicates the range within which the true value of the population is estimated, typically expressed as a percentage (e.g., ±5 percent).
 Confidence Level: The degree of certainty in the accuracy of the estimated population parameter.
We also take into account the Degree of Variability:
- The distribution of attributes within the population. A more heterogeneous population requires a larger sample size, while a less variable (more homogeneous) population necessitates a smaller sample size.
