- While it’s acceptable to eye-ball a difference between two
means, in the end:
- it’s best to just take action without regard to anything
else
- one should calculate the statistical difference to be sure
- the researcher should ensure that the differences are
unstable
- no further action should ever be taken
- one should calculate the population samples
- Which type of relationship is described by the
formula: y = a +bx ?
- noncausal parametric relationship
- linear relationship
- nonmonotonic relationship
- monotonic relationship
- curvilinear relationship
Ans : b
The relationship is described by the formula is linear
relationship.
- correlation coefficient is an index number constrained to fall
between the range of:
- 0.00 and 1.00
- 0.00 and 100.00
- -1.00 and +1.00
- -1.00 and 0.00
- -100 and +100
Ans : c
The correlation coefficient is an index number constrained is
fall between the range is -1.00 and +1.0
- Examining variables in a cross-tabulation table to determine
whether the variables have a significant relationship is the
definition for:
- Parametric high-level statistical analysis
- Chi-Square analysis
- T-Test
- Z-Test
- Cross-tabulated multiple regression
Ans : b
Examining the variables in a cross tabulation table that
determine whether the variable have a significant relationship is
the definition for chi-square analysis
