FAQs on Statistics and Probability Mock Test for JEE Main 2025-26
1. What is the difference between statistics and probability?
The main difference is that probability predicts the likelihood of future events based on known parameters, while statistics analyzes actual data to infer information about populations. In summary, probability deals with forecasting chances, and statistics deals with interpreting data.
2. What are the types of data in statistics?
In statistics, data can be classified as qualitative (categorical) or quantitative (numerical). Quantitative data can further be divided into discrete (countable) and continuous (measurable) data.
3. How do you calculate the mean, median, and mode of a data set?
To find central tendency:
Mean: Add all data values and divide by the total count.
Median: Arrange data in order and find the middle value.
Mode: Identify the value that appears most often in the set.
4. What is the probability of getting a head when tossing a fair coin?
Probability is calculated as the number of favorable outcomes divided by the total possible outcomes. For a fair coin, the probability of getting a head is 1/2 or 0.5.
5. Explain the terms sample and population in statistics.
A population represents the entire group under study, while a sample is a subset of the population selected for analysis. Statistical conclusions about the population are often made based on the sample data.
6. What is a random variable?
A random variable is a variable whose value is determined by the outcome of a random event. It can be classified as discrete (having specific values) or continuous (taking any value in a range).
7. How do you find the probability of two independent events occurring together?
If two events are independent, their joint probability is the product of their individual probabilities: P(A and B) = P(A) × P(B).
8. What is the difference between permutation and combination?
A permutation counts the number of ways to arrange items where order matters. A combination counts selections where order does not matter. Use permutations when order is important, and combinations when it is not.
9. What are the main measures of dispersion in statistics?
The primary measures of dispersion are range, variance, and standard deviation. They indicate how spread out or scattered the data values are from the mean.
10. Define mutually exclusive events with an example.
Events are mutually exclusive when they cannot occur at the same time. For example, when rolling a die, getting a 2 and getting a 4 are mutually exclusive because both outcomes can't happen in the same roll.
11. How is probability used in real-world decision making?
Probability is used to assess risk, predict trends, and make informed decisions. For example, it helps in insurance premium calculation, weather forecasting, and quality control in manufacturing processes.
12. What is the importance of normal distribution in statistics?
The normal distribution is important because many real-world variables naturally follow this symmetrical, bell-shaped pattern, which enables reliable statistical analysis and prediction using measures like mean and standard deviation.
