WebStep 1. Interpret the reliability coefficient: I looked at the value of Cronbach's alpha for the instrument, which was -1.669. Since Cronbach's alpha measures the internal consistency of a scale, a negative value indicates that the average covariance among items is negative, violating the assumptions of the reliability model. Step 2. WebFirstly, deleting items with low corrected item-total correlations could improve the scale's reliability. Secondly, adding more items to the scale could also increase reliability. Lastly, conducting a factor analysis could help identify the underlying factors that the … WebJul 15, 2024 · The Correlation Coefficient. As a refresher, Pearson’s correlation coefficient, which is traditionally denoted by r, shows the relationship betweentwo variables, and is a measure that varies from −1.00 to 1.00. When r=−1.00 it means that we have a perfect negative relationship, and when r=1.00 it means we have a perfect positive … tsh products
