Being objective is also important to ensure data are not biased which affects the reliability of the data. Measures to ensure validity of a research include, but not limited to the following points: a) Appropriate time scale for the study has to be selected; b) Appropriate methodology has to be chosen, taking into account the characteristics of the study; c) The most suitable sample method for the study has to be selected; d) The respondents must not be pressured in any ways to select specific choices among the answer sets.
