If the result is statistically not significant this is not a weakness but shows that the variables being examined have no effect on each other, • Instruments: items in an instrument are not testing what they should be testing, or the reliability of the instrument is not mentioned. • Practical implications are not mentioned. • Limitations: failure to mention limitations. • The limitations that the researcher mentions should not be considered weaknesses because he/she admits them...
