2. If we have a large voluntary response sample consisting of weights of subjects who chose to respond to a survey posted on the Internet, can a graph help to overcome the deficiency of having a voluntary response sample?
Choose the correct answer below.
- No, a graph cannot help to overcome the deficiency. If the sample is a bad sample, there are no graphs or other techniques that can be used to salvage the data.
- No, a graph cannot help to overcome the deficiency. Before graphing, all inaccurate values and outliers must be removed from the data set.
- Yes, a graph can help to overcome the deficiency. Any graph that is given with a sufficiently accurate description of any deficiencies in the sampling technique is no longer considered biased.
- Yes, a graph can help to overcome the deficiency. Certain graphs that hide any specific values in the data, such as pie charts, can be used to hide deficiencies in the sampling technique.
