Answer to Question 1

B

Answer to Question 2

The first type of error is systematic error, which affects measurement in a constant way. Sometimes personality traits or other stable characteristics of individuals add systematic error to the measurement process. Differences in how surveys are administered can also introduce systematic error into a project. The second type of error is random error, which is due to transient aspects of the person or measurement situation and which affects the measurement in irregular ways. Random error is present when we repeat a measurement on an individual and do not get the same scores as the first time we did the measurement, even though the characteristic being measured has not changed. The situation surrounding the measurement also affects the score in random ways.
