Then you’ve reached the right place
Why you need to calculate Sample size important?
Finding the proper statistical power analysis is a significant part of the Quantitative study and it helps to decide how much sample size is to be taken for calculating in the statistical test to judge more reliable and accurate variables. Our team of statistician calculates power and sample size based on the effect size, population size, the alpha significance criterion (α), statistical power or the chosen or implied beta (β).

Why you need to calculate Sample size important?
Statistical sample size calculation mainly helps to generate how much sample/data needed to make an accurate decision on research. Sample size calculations can help you determine how large sample size you need to create to achieve accurate statistical outcomes. The purpose of power analysis and sample size calculation is to determine if you will have enough power and determining the appropriate sample size, hence, utilizing too large (may waste money, resources and time) or too small (inaccurate result) may be avoided. Without sample calculations, you will not be assured that if your proposed sample size is too large or small.
For example, when comparing two-target population and reached a sample size less than 30, we use one of the statistical analysis test /power analysis –T-test. Similarly, if the sample size is >30, then we utilize the z-test. In general, if the targeted population size is smaller one, then we use a bigger sample size, and if the targeted population size is larger one we require a smaller sample size. In addition, sample size calculation would also differ with different margins of errors.

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
In this analysis, three major factor like sample size, alpha, beta and effect size can be calculated.
- 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
Further, we also look out for
The Level of Precision- sampling error- range - the true value of the population estimated to be.
- Expressed in percentage points (e.g., ±5 percent).
Degree of Variability
- the distribution of attributes the more heterogeneous a population, the larger the sample size while the less variable (more homogenous), the smaller the sample size
