Table 1

The descriptive data for failure load values of test groups.

Test group	Number	Mean (N)	Standard deviation (N)	Min. (N)	Max. (N)	95% confidence interval
						Lower bound	Upper bound
NC	11	364.28^a	114.88	219.30	616.50	−296.46	432.10
SC	11	324.57^a	89.25	220.10	471.4	−271.88	377.53
LC	10	207.26^b	90.62	110.10	369.00	−151.05	263.47

Items in the rows with dissimilar letters are significantly different at 95% level of confidence; ^avalues are nonsignificantly different at P = 0.81; ^bvalue is significantly different at P = 0.004.
