Understanding the Dependent t Test

subjects, simple repeated-measures or within-groups, or correlated groups) assesses whether the mean difference between paired/matched observations is significantly different from zero. That is, the dependent-samples t test procedure evaluates whether there is a significant difference between the means of the two variables (test occasions or ...

CPT AND SPT BASED LIQUEFACTION TRIGGERING PROCEDURES

procedures began with work by Zhou (1980) using observations from the 1978 Tangshan earthquake and was followed by Seed and Idriss (1981) and Douglas et al. (1981) who proposed the use of correlations between SPT and CPT penetration resistances to convert the then available SPT-based liquefaction triggering charts for use with the CPT.
