Which of the following statements is true of hypotheses? They are developed prior to data collection. They are used to convert measures of dispersion into measures of central tendency. They can be derived from the current business situation but not from previous research theory. They are proven suppositions that explain facts or phenomena.

Question
Which of the following statements is true of hypotheses? They are developed prior to data collection. They are used to convert measures of dispersion into measures of central tendency. They can be derived from the current business situation but not from previous research theory. They are proven suppositions that explain facts or phenomena. They are used to validate data in the data preparation process.
Solution
The statement that is true of hypotheses is: "They are developed prior to data collection."
Hypotheses are proposed explanations or predictions that are based on existing knowledge. They are formulated before data collection begins, and they guide the research process. The purpose of a hypothesis is to test it against the data collected to either support or reject it.
The other statements are not generally true of hypotheses. They are not used to convert measures of dispersion into measures of central tendency, they can be derived from both the current business situation and previous research theory, they are not proven suppositions (they are proposed explanations that need to be tested), and they are not used to validate data in the data preparation process.
