Put the steps of construction of summated rating attitude scale in a correct order.

(A) Selection of final items

(B) Calculation of item wise critical ratio

(C) Item writing

(D) Administration for final try out

(E) Pre try out

Choose the correct answer from the options given below:

The correct answer is - (C), (E), (D), (B), (A)

Key Points

• Item writing
  • The first step involves creating or writing items that reflect the construct being measured.
• Pre try out
  • Preliminary testing of the items is conducted to identify any issues and make necessary revisions.
• Administration for final try out
  • The refined items are administered to a larger sample to gather data for analysis.
• Calculation of item wise critical ratio
  • Item analysis is performed to calculate the critical ratio and determine the items' effectiveness.
• Selection of final items
  • The final selection of items is based on the analysis to ensure reliability and validity.

Additional Information

• Summated Rating Scale
  • Also known as the Likert scale, it is widely used for measuring attitudes by summing the responses to multiple items.
  • Each item typically has a set of ordered response options indicating varying levels of agreement or disagreement.
• Critical Ratio
  • It is a statistical measure used in item analysis to determine the discriminative power of an item.
  • Items with higher critical ratios are considered more effective in differentiating between high and low scorers.
• Reliability and Validity
  • Reliability refers to the consistency of the scale, while validity refers to how well the scale measures the intended construct.
  • Both are crucial for ensuring the accuracy and usefulness of the scale in research and practice.
