Lecture 3: Statistical sampling uncertainty
... across the samples, then a useful strategy to estimate statistical uncertainty is to break the time series up into chunks which are long enough not to be strongly correlated with each other, perform the data analysis on each chunk separately, and compare the results for different chunks. In testing ...

In statistics, mean has two related meanings:
... Step 6. Divide the sum of squares by the number of data points (5). The result is 31.04 square inches. This is the mean of the squared deviations. Other names for this number are Mean Square or Variance. Variance is much-used in statistical work. Step 7. Since variance is still a squared value, we n ...

... Is symmetric about the mean. The mean, median, and mode are equal to 0 and are located at the center of the distribution. Curve never touches the x-axis. Variance is greater than 1. As sample size increases, the t distribution approaches the standard normal distribution. Has n-1 degrees of freedom. ...

Using our results, botanists might carry out further studies with seeds in space looking for a possible way to produce larger plants. The example above is called a one-tail test because the alternate hypothesis created an emphasis on one ...
