Скачать или смотреть 8.5: Finding the Mean, Median, Mode | Probability & Statistics (Walpole, Myers & Myers)

Solved Exercise 8.2 from Probability & Statistics for Engineers & Scientists (9th Edition) by Ronald E. Walpole, Raymond H. Myers, Sharon L. Myers, Keying Ye, complete step-by-step solution of the mean, median, and mode of a series of numbers.
This video is perfect for engineering students, data scientists, and anyone preparing for exams or interviews who wants a clear, practical demo of approximating binomial probabilities with the normal curve.

What you’ll learn in this video
• What is the mean, the median, and the mode.
• how to calculate them.
• What are the different steps of their calculation.

8.5 The numbers of incorrect answers on a true-false competency test for a random sample of 15 students were recorded as follows: 2,1,3,0,1,3,6,0,3,3,5,2,1,4, and 2. Find
(a) the mean;
(b) the median;
(c) the mode.

Why watch this if you want high value
This problem is a core example of approximating discrete distributions by continuous ones — a fundamental skill across probability, statistical inference, data science, machine learning, reliability engineering, and quality control. Great for midterms, finals, and practical modeling decisions.
