We can't help with the "is this correct" because that is predicated on the scientific question at hand and something only you and subject-matter experts can determine. If you are naive to statistics and their role in your analysis, I suggest you consult a statistician...

Create a section on your worksheet for summary statistics for your independent samples. Calculate the sum, the n-value (or sample size), and the mean of the scores for each of the independent samples. Label each calculation with "sum," "n" and "mean," respectively. Calculate the degrees ...
How to Calculate Statistical Significance Statistical significance is a cornerstone of data analysis, helping researchers, analysts, and businesses alike determine whether the results of an experiment or study are meaningful or if they could have occurred by random chance. In this extensive guide, we ...
In statistics, the parameters of a linear mathematical model can be determined from experimental data using a method called linear regression. This method estimates the parameters of an equation of the form y = mx + b (the standard equation for a line) u
While it is often impossible to sample an entire population of organisms, you can make valid scientific arguments about a population by sampling a subset. In order for your arguments to be valid, you have to sample enough organisms to make the statistics
If you have knowledge or estimates of any three, you can calculate the fourth element. Statistical power. Sample size: the fewest number of observations required to spot an effect of a certain magnitude with a given power level. Significance level (alpha): this is the maximum risk you’...

How to calculate your market size Calculating your market size shouldn’t be complicated. In fact, it can be done in three simple steps: 1. Define your target audience and Total Addressable Market (TAM) Your target customers are the people for whom your product or service solves a specific ...
This test is used in scenarios where the sample size of the data sets are same, or the variance of the data sets are similar. To calculate the t-value for an equal variance test, you can use the following formula: t=mean1-mean2n1-1)×var12+(n2-1)×var22n1+n2-21n1+1n2 ...
