The Analysis of the Data from a Study Indicates That

The analysis of the data from a study indicates that there was a significant difference between two groups, which were randomly selected and composed of 300 subjects each. The instruments measuring stress, mood, and various scaled measures of emotion were well normed, widely tested, and suitable. The researcher begins interpretation of the data and discovers that during data collection one of the assistants had recorded the demographic item "household size" incorrectly for 25 subjects, understanding the item as "number of people who live with you." The researcher makes a decision to work with the data that are recorded for this variable, treating the faulty entries as missing values. How should the researcher present this information in the discussion section of the report?

A) As a statistical conclusion validity limitation
B) As a serendipitous finding
C) As a construct validity limitation
D) It is unnecessary to present this information in the report because the researcher is allowed to clean the data in this way.
