Slide 1 - “Mean, Median, & Mode of Lines of Code Written Per Day”
Slide 2 - My Introduction
As a computer science student, I measure my productivty by the number of lines of code that I write per day when I have a coding project to submit. This presentation explores the concepts of mean, median, and mode using a sample dataset of the lines of code written over the week.
Slide 3 - What exactly is Mean, Mode, & Median?
The mean is the average:
\[ \text{Mean} = \frac{\sum x_i}{n} \] \[ \text{Median} = \begin{cases} x_{\left(\frac{n+1}{2}\right)}, & \text{if } n \text{ is odd} \\ \frac{1}{2} \left( x_{\left(\frac{n}{2}\right)} + x_{\left(\frac{n}{2} + 1\right)} \right), & \text{if } n \text{ is even} \end{cases} \]
The median is the middle value after data is sorted.
Lastly, the mode is the most frequently occuring data point or value.
