FAQs on Basic Problems: Average Video Lecture - Quantitative Techniques for CLAT

1. What is the formula for calculating the average?
Ans. The formula for calculating the average (mean) is to add all the numbers together and then divide by the count of those numbers. Mathematically, it can be expressed as: Average = (Sum of all values) / (Number of values).
2. How do you calculate the average of a set of numbers?
Ans. To calculate the average of a set of numbers, first sum all the numbers together to get a total. Then, count how many numbers there are in the set. Finally, divide the total by the count of numbers to find the average.
3. What is the difference between average, median, and mode?
Ans. The average is the sum of all values divided by the number of values. The median is the middle value when all numbers are arranged in order. The mode is the value that appears most frequently in a dataset. Each measure provides different insights into the data.
4. Can the average be affected by extreme values (outliers)?
Ans. Yes, the average can be significantly affected by extreme values or outliers. If there are very high or very low numbers in the dataset, they can skew the average, making it unrepresentative of the general data.
5. How do you find the average of fractions or decimals?
Ans. To find the average of fractions or decimals, you follow the same process: sum all the fractions or decimals to get a total. Then, divide that total by the number of values. Make sure to convert fractions to a common denominator if necessary before summing.
