Understanding Statistical Distributions

The video tutorial by Krishnak on his YouTube channel discusses statistical distributions, focusing on right skewed, symmetrical, and left skewed distributions. It provides examples for each type, such as wealth distribution for right skewed and lifespan for left skewed. The video also explains the relationships between mean, median, and mode in these distributions. Krishnak emphasizes the importance of understanding these concepts with practical examples, especially for interview preparation.

What is the main topic of the video introduced by Krishnak?

• Machine learning algorithms

Which of the following is a classical example of a right skewed distribution?

• Age distribution

• Wealth distribution

• Height distribution

• Temperature distribution

In a right skewed distribution, which side of the histogram is elongated?

• Left side

• Both sides

• Right side

• Neither side

What is another name for symmetrical distribution?

• Right skewed distribution

• Left skewed distribution

• Bimodal distribution

• Normal distribution

Which of the following distributions is typically followed by height data?

• Uniform distribution

• Symmetrical distribution

• Left skewed distribution

• Right skewed distribution

What is a classical example of a left skewed distribution?

• Height distribution

• Temperature distribution

• Lifespan of human beings

• Wealth distribution

In a left skewed distribution, which side of the histogram is elongated?

• Both sides

• Right side

• Left side

In a right skewed distribution, how do the mean, median, and mode relate?

• Mean < Median < Mode

• Mean > Median > Mode

• Mean = Median = Mode

• Mean < Mode < Median

In a symmetrical distribution, how do the mean, median, and mode relate?

• Mean < Median < Mode

• Mean > Median > Mode

• Mean = Median = Mode

• Mean < Mode < Median

In a left skewed distribution, which measure of central tendency is the highest?

• All are equal

• Mean
