Final Result of Significant Difference In cell B13, the P(T = t) two-tail is less than the alpha value of 0.05. We can conclude that the means of our two trials differ by a statistically significant amount, and we can say the difference is significant. Note:T-tests are resilient to d...

Significant Difference: The significant differencesimply means that two sets of data are significantly different. In statistics, we consider that there is a 5% probability of this happening by chance. If this is not the case then the datasets are different. A Null Hypothesis assumes that two mean...
outliers in single columns, it has some significant limitations. The biggest limitation is an inability to capture different shapes within our data. For example, a point in a column may not be an outlier in a one-dimensional boxplot, but it may become an outlier in a two-dimensional ...
parameter is hypothesized to be greater than or less than some value, a one-tailed test is used. When no direction is indicated in the research hypothesis, a two-tailed test is used. A two-tailed test will show whether or not there is a difference in the values of the variables ...
How to find a coefficient of variation in Excel. You can calculate the coefficient of variation in Excel using the formulas for standard deviation and mean. For a given column of data (i.e. A1:A10), you could enter: “=stdev(A1:A10)/average(A1:A10)) then multiply by 100. ...

Oftentimes, outliers pose very big problems in statistics. For instance, in the sample problem, the value 100 posed a significant issue. The standard deviation was raised much higher than it would have been without this value being present. This means that this number might have also made the...
Statistical significance is a measure ofwhether your research findings are meaningful. More specifically, it’s whether your stat closely matches what value you would expect to find in an entirepopulation. As a simple example, let’s say you worked for a polling company and asked 120 people ho...
