FINAL EXAM QUESTIONSSECTION TWOQuestion 5a)Split half reliability analysis refers to the extent to which a scale gives the same resulteven after multiple repetitions. The data is dividing into halves thus reliability in the twohalves. The output is alpha 0.9051 refers to extent to which its consistent measure ofconcept.b)Cronbach’s test to determine if there existed biasness in splitting.c)The alpha 0.9051>0.7 thus high reliabilityQuestion 6a)Test- Retest is to construct a reliable measurement scale, to improve the scales and finallyevaluate the scale in use.b)Calculate the coefficient alpha which will identify the reliability of the scales.c)The reliability coefficient 0.6559 <0.7 thus the scale are less reliable.Question 7a)Pearson correlation measures linear correlation between two variables. When output is 1,positive linear correlation. When output is 0, no linear correlations while -1 indicates anegative linear correlation.b)Correlation between satisfaction and unreliability is -.5 thus weak negative correlation,intent to buy .764 thus positive correlation and friendly 0.18 hence weak positivecorrelation.Correlation between unreliability and intent to buy and friendly -.35 and 0.5 are weaknegative and positive correlations respectively.Correlation between intent to buy and friendly are 0.007 which is weak positivelycorrelated.Correlation between satisfaction and friendly is weakly positively correlated.c)The output is logical since all these values are between 1 and -1. They are within therange.d)The unreliability of the supply company gave dissatisfaction to the buying company.Question 8a)Pearson correlation measures linear correlation between two variables. When output is 1,positive linear correlation. When output is 0, no linear correlations while -1 indicates anegative linear correlation.b)Likelihood to purchase competitors brand and product performance are negativelycorrelated. Purchasing competitors brand lowers performance of our product.
