FAQs on Statistics And Probability JEE Main Mock Test 2025-26: Practice & Assessment
1. What is the difference between statistics and probability?
The main difference is that statistics involves collecting, analyzing, and interpreting real-world data, while probability deals with predicting future outcomes based on mathematical models or likelihoods. Probability is theoretical and forecasts the chance of events, whereas statistics summarizes and infers from actual data.
2. Define mean, median, and mode with examples.
Mean is the average of a set of numbers (sum of values divided by total count). Median is the middle value when data are arranged in order. Mode is the most frequently occurring value in a data set.
Example: For 2, 4, 4, 5, 7 — Mean = (2+4+4+5+7)/5 = 4.4; Median = 4; Mode = 4.
3. How do you calculate the probability of an event?
To find the probability of an event, divide the number of favorable outcomes by the total possible outcomes. Mathematically, Probability = Number of favorable outcomes / Total number of possible outcomes. For example, in tossing a fair coin, probability of heads = 1/2.
4. What is the difference between discrete and continuous data?
Discrete data take specific values (like number of students), while continuous data can take any value in a range (like height or weight). Discrete is countable; continuous is measurable with infinite possible values within intervals.
5. Explain the concept of random variable in probability.
A random variable is a quantity that can take different values based on the outcome of a random experiment. It assigns a real number to each possible outcome, such as the number showing up when a dice is rolled. Random variables can be discrete or continuous.
6. What are mutually exclusive events?
Two events are mutually exclusive if they cannot occur at the same time. For example, when tossing a coin, getting heads and tails in a single toss are mutually exclusive events. If A and B are mutually exclusive, then Probability (A and B) = 0.
7. How is the standard deviation different from variance?
The variance measures the average squared deviation from the mean, denoted as σ², while the standard deviation is the square root of variance (σ) and represents dispersion in the same units as the data. Standard deviation is more intuitive for interpreting spread relative to the mean.
8. What is a cumulative frequency distribution?
A cumulative frequency distribution shows the running total of frequencies up to each class interval or data value. It helps in understanding the number of observations below or within a certain value and is useful in constructing ogives and analyzing percentiles.
9. Give an example of a real-life application of probability in daily life.
In daily life, probability is used in weather forecasting (chance of rain), insurance (risk assessment), games of chance (lottery, cards), and decision-making under uncertainty. For instance, a weather report stating a 70% chance of rain uses probability concepts.
10. Describe the difference between population and sample in statistics.
A population is the entire set of items or individuals under study, while a sample is a subset of the population selected for analysis. Statistical inference is often made from samples to draw conclusions about the whole population.
11. What is the importance of probability in statistics?
Probability provides the theoretical foundation for statistics. It is crucial for making predictions, testing hypotheses, estimating parameters, and calculating risks. Probability helps interpret statistical results and quantify uncertainty in conclusions.
12. What are the common types of data representation in statistics?
Common forms of data representation include bar graphs, histograms, pie charts, ogives, and frequency polygons. These methods help visualize patterns, compare groups, and summarize large datasets easily for analysis and interpretation.
