Power Analysis Assistance

Niche help in estimating the number of observations

Performing power analysis plays a vital role in dissertation preparation. It establishes whether the desired sample size is sufficiently large enough for statistical relevance. A well-performed power analysis spells the difference between a valuable and invaluable research. However, this process can be challenging and also act as a roadblock to perfect dissertation. The statisticians at Florida Dissertation have immense experience in conducting the power analysis and can help you perform the same without any error.

Power

It is nothing but the probability of determining true significance of a value (or probability of type-II error). Power is generally set to 0.80.

Alpha

It is the probability of identifying the significance level to pre-specified value ( or probability of type -I error). The alpha value is generally 0.05.

Effect size

This is nothing but the change in a parameter of interest determined by an experiment. Effect size is calculated by using methods such as Pearson’s correlation coefficient.

Sample size

It can be known and fixed. Sample size is the number of observations in the given sample and is often represented by “N”.

How do our statisticians Help You?


Check for statistical relevance

Irrespective of the type of subject, our statisticians refer to parameters of literature in your field of study and determine if the sample size is significantly relevant.


Determine a suitable test

In addition to determining effect size and other factors, our team will also help you in choosing the most appropriate statistical test for the power analysis process.


Perform priori & post-hoc analysis

Besides performing the power analysis, we can help you conduct a precise priori or post-hoc analysis and deliver significant results.


Conduct pilot study

Many times, pilot study is suitable for determining the exact sample size. We can help you perform fully-adequate pilot study for your research.
