It has been shown that, probably as a result of the Central Limit Theorem, the use of parametric methods, such as a t-test, when comparing means are fairly robust against violations of non-normality [ 16].
As seen from the Figure 2, the estimates of the mean were fairly accurate and useful.
For internal/external rotation, the group mean was fairly similar, up to 25 degrees of flexion.
Therefore, although the graph shows a decline in absolute variability and noise over time, the relative variability (variation around the annual mean) was fairly stable.
The summary statistics of time spent according to resubmission status and lead researcher in table 2 show that the mean times were fairly similar.
A person gets a reputation as dependable or undependable by either doing "well to make it work or happen" or not quite dependable enough... "You tried!" could mean: "You were fairly successful -- but still not quite good enough".
The test results showed that all the variables' skewness and kurtosis were less than +3 and greater than −3, which meant that they were fairly normally distributed (Tabachnick & Fidell 1989).
At baseline, mean service costs were fairly similar between the groups (Table 3), but higher informal care costs for the CBT group (£4378 vs. £2903), contributed to much more societal costs at baseline compared to the SL group.
This means that the articles were "fairly difficult" and "difficult" to read.
Temperatures were fairly constant (mean temperature 19/20 °C, daily maximum 26/27 °C, standard deviation of mean temperature 1·3/1·8 °C) during these replications.
