Module 4 – Introduction to Research (Teaching Notes) 4.1 Meaning, Need, Significance, Characteristics and Scope of Research Meaning of Research Research is a systematic and scientific process of collecting, analyzing and interpreting information to find answers to problems or questions . In simple words, research means careful investigation to discover new knowledge or verify existing knowledge . Example: A teacher studying why students are weak in mathematics and finding ways to improve their performance. Need of Research Research is needed because: To discover new knowledge To solve problems To improve teaching and learning methods To test existing theories To support decision making Example: Research helps teachers understand which teaching method is most effective for students .

1️⃣ Percentile Percentile is a value that shows the percentage of scores below a particular score in a group . In simple words: It tells how many students scored less than a particular score . Example Suppose 100 students wrote an exam. If a student is in the 80th percentile , it means: 👉 The student scored higher than 80 students . Only 20 students scored higher . So, 80th percentile = score above 80% of students 2️⃣ Percentile Rank Percentile Rank is the percentage of scores that fall below a particular score . It shows the position of a student in comparison with others . Formula PR = \frac{B + 0.5E}{N} \times 100 Where: PR = Percentile Rank B = Number of scores below the score E = Number of scores equal to the score N = Total number of scores 3️⃣ Simple Example Marks of students: 20, 30, 40, 50, 60 Find Percentile Rank of 40 Below 40 → 2 scores (20,30) Equal to 40 → 1 score Total students N = 5 PR = \frac{2 + 0.5(1)}{5} \times...
