Source of measurement error

Assignment Help Basic Statistics
Reference no: EM1389593

According to the slide presentation for chapter 12 for the Cooper and Schindler text, there are four sources of measurement error:

1) errors on the part of respondents/study participants;

2) errors due to situational factors that affect study results;

3) errors on the part of the measurer/researcher; and 4) errors in the measurement instrument/survey.

Provide two examples for each source of measurement error and include how each example might likely influence research results.
