Given the following information for a one-year project, answer the following questions. Recall that PV is the planned value. EV is the earned value, AC is the actual cost, and BAC is the budget at completion.
PV = $23,000
EV = $20,000
AC = $25,000
BAC = $120,000
a. What is the cost variance, schedule variance, cost performance index (CPI), and schedule performance index (SPI) for the project?
b. How is the project doing? Is it ahead of schedule or behind schedule? Is it under budget or over budget?
c. Use the CPI to calculate the estimate at completion (EAC) for this project. Is the project performing better or worse than planned?
d. Use the schedule performance index (SPI) to estimate how long it will take to finish this project.
e. Sketch the earned value chart based on this project

Reliability and validity reliability and validity are two important considerations that must be made with any type of data collection. reliability refers to the ability to consistently produce a given result. in the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways. unfortunately, being consistent in measurement does not necessarily mean that you have measured something correctly. to illustrate this concept, consider a kitchen scale that would be used to measure the weight of cereal that you eat in the morning. if the scale is not properly calibrated, it may consistently under- or overestimate the amount of cereal that’s being measured. while the scale is highly reliable in producing consistent results (e. g., the same amount of cereal poured onto the scale produces the same reading each time), those results are incorrect. this is where validity comes into play. validity refers to the extent to which a given instrument or tool accurately measures what it’s supposed to measure. while any valid measure is by necessity reliable, the reverse is not necessarily true. researchers strive to use instruments that are both highly reliable and valid.
