Expert Academic Advice to Design your Experiments

Statistical power analysis comes at the most crucial phase of a dissertation, where you have to present the results of your hard earned research in the form of a diligently calculated data. Do you, often deal with questions like:

  • Is the data analysis chapter would ever be completed?
  • Who will help me with the sample size estimation?
  • How to figure out the difference between inferential and descriptive analysis?
  • What about STATA, E-Views, and SPSS?

Before you calculate the risk of choosing a bad sample, it would be better to get an answer to all those questions that results in a sampling error.

Make your concepts clear about Power Analysis

Students, seeking help with their dissertation statistics often put a question related to the size of the sample, Our team of 150+ research consultants can help you to find the answers easily. Sampling estimation depends on several factors like:

  • The purpose of the study.
  • Cost consideration about the study.
  • Minimum level of precision to be accepted.
  • Variables related to population size.
  • Along with the method of sampling.

The planned samples are estimated during the power analysis. If you haven't conducted a pilot test yet, then the best practice would be to consider the sample size of the relevant literature. So far, our statistical consulting services have helped 2000+ students in various academic disciplines.

How to determine the Sample Size

Our expert statisticians practice the following aspects with an attentiveness, to estimate the samples you have planned.

1. Initially, we start with a conjecture that a random sample is your planned design and for complex designs we estimate the variances like subpopulations and clusters.
2. Next we measure the size of the sample for appropriateness. This, technically, depends on the methods of statistical analysis. For instance:

  • For descriptive statistics: Often used for larger sample sizes, the size is determined without any rigorous considerations.
  • For thorough state impact evaluations, such as multiple regression, co-variance, and log-linear analysis, we choose a good sample size. Such as n=150+
  • When providing comparative analysis, we adjust the sample size to accommodate the subgroups.

3. Then, we obtain the required formulas to generate the number of responses. Usually, for surveys and personal interviews, we add 25% more to the planned sample size.

If you can't estimate the accurate sample size, then we can conduct a power analysis study for you. With our expert help, you can complete the chapter within 2-3 weeks without spending too much money.
