Questions to Assist in Validity of Data Collection Instrument

To aid in the securing of validity for quantitative research here are a few questions to ask during the creation of a quantitative study:

  • what prior studies have used this particular instrument?  What were the outcomes?
  • Is the use of my instrument for data collection of similar purposes?
  • Do my interviews verify my data collection instrument? (Creswell, 2012, p. 163)
