TABLE 11-8 An Important Factor in Selecting Database Software Is the Time

question 57

True/False

TABLE 11-8
An important factor in selecting database software is the time required for a user to learn how to use the system. To evaluate three potential brands (A, B and C) of database software, a company designed a test involving five different employees. To reduce variability due to differences among employees, each of the five employees is trained on each of the three different brands. The amount of time (in hours) needed to learn each of the three different brands is given below:

Below is the Excel output for the randomized block design:

-Referring to Table 11-8, the randomized block F test is valid only if there is no interaction between the amount of time needed on the 3 brands of software and the 5 employees.

Definitions:

Delayed Reinforcers

Rewards that do not immediately follow a behavior but occur after some time, still affecting the likelihood of the behavior's recurrence.

Variable-Interval Schedules

A reinforcement schedule in experiments where a response is rewarded after an unpredictable amount of time has passed, used to study learning and behavior.

Primary Reinforcers

Innate reinforcing qualities like food, drink, and pleasure that fulfill basic biological needs and do not depend on learning to be effective.

Spontaneous Recovery

The reappearance of a conditioned response after a period of rest or no exposure to the conditioned stimulus.
