Important Questions from Statistics

1multiple choice

If mean = 25, median = 20, what type of distribution is this likely to be?

Show answer

Positively skewed

Step 1: Compare mean and median. Step 2: When mean > median (25 > 20), the distribution is positively skewed. Step 3: This means the tail extends more towards higher values, pulling the mean above the median.

2multiple correct

Which of the following are measures of central tendency?

Show answer

Mean, Median, Mode

Step 1: Central tendency measures represent the center of data. Step 2: Mean (average), Median (middle value), and Mode (most frequent value) all indicate central position. Step 3: Range and Standard Deviation measure spread, not central tendency.

3multiple choice

Calculate the mean using direct method for: Class: 0-10(f=2), 10-20(f=5), 20-30(f=3)

Show answer

15

Step 1: Find class marks: 5, 15, 25. Step 2: Calculate Σfixi = 2×5 + 5×15 + 3×25 = 10 + 75 + 75 = 160. Step 3: Σfi = 2 + 5 + 3 = 10. Step 4: Mean = Σfixi / Σfi = 160/10 = 15.

4multiple choice

Find the median for data: 4, 6, 8, 10, 12, 14

Show answer

9

Step 1: Data is already arranged: 4, 6, 8, 10, 12, 14. Step 2: n = 6 (even number). Step 3: Median = (n/2)th + (n/2 + 1)th / 2 = (3rd + 4th)/2 = (8 + 10)/2 = 18/2 = 9.
