Match each entry in List-I to the correct entries in List-II.
| List-I | List-II | ||
|---|---|---|---|
| (P) | The mean of the above data is | (1) | 2.5 |
| (Q) | The median of the above data is | (2) | 5 |
| (R) | The mean deviation from the mean of the above data is | (3) | 6 |

Frequently Asked Questions
Q1. Is statistics a branch of probability?
Statistics and probability are related fields in mathematics but have different applications. Probability involves predicting future events, while statistics is not a branch of probability there are some differences.
Q2. Who is the father of statistics?
Sir A. Ronald Fisher is considered the father of Statistics. He made contributions to the fields of statistics, experimental designs, statistical testing, and hypothesis testing.
Q3. What are the limitations of statistics?
Statistics is useful for analyzing, interpreting, and calculating data, still, there are some limitations of statistics that affect the accuracy of data.
- Statistics deal with groups of data and it cannot provide information related to individual cases.
- Statistical data can be incorrect if the data collection is poor and incorrect methods are applied while calculation.
- Statistics can only analyze quantitative data, abstract qualities like emotions, morals, ethics, and empathy can not be analyzed through statistics.
Q4. What is a safe score for JEE Advanced exam?
Fundamentally safe score in JEE Advanced 2025 is reliant, on difficulty level and cutoff patterns. In general, 40-50% of total marks can fetch a rank within the IIT admission category. For any top IITs (IIT Bombay, IIT Delhi, IIT Madras), a rank below 2500 is desired. Monitor the category-wise cutoff patterns and last year JEE Advanced cutoffs.
Q5. What is the difficulty level of JEE Advanced ?
JEE Advanced is particularly famous for being of high difficulty, challenging the conceptual clarity, application-based solving of problems, and time management. The mathematics part includes higher-order algebra, calculus, and coordinate geometry; physics demands an understanding of electromagnetism, mechanics, and modern physics at a deeper level; and chemistry has a combination of organic reaction mechanisms, physical chemistry calculations, and inorganic memorization. The test aims to check critical thinking and application of multiple concepts.
