Consider the widget exchange. Suppose that each widget contract has a market value of $0 and a notional value of $100. There are three traders, A, B, and C. Over one day, the following trades occur:

A long, B short, 5 contracts. A long, C short, 15 contract. B long, C short, 10 contracts. C long, A short, 20 contracts.

a. What is each trader’s net position in the contract at the end of the day? (Calculate long positions minus short positions.)

b. What are trading volume, open interest, and the notional values of trading volume and open interest? (Calculate open interest as the sum of the net long positions, from your previous answer.)

c. : C long, B short, 5 contracts?

d. How would you expect the measures in part (b) to be different if each contract had a notional value of $20?

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.
