Key Concepts

Bar Graph

A bar graph is a graphical representation of data where the data is displayed with rectangular bars. The length or height of the bar is proportional to the value it represents, making it easy to compare different categories. This technique is fundamental in representing categorical data clearly and accurately.

Vertical Bar Graph

A vertical bar graph is a type of bar graph where the bars extend vertically. Typically, the horizontal axis represents the categories, and the vertical axis represents the values or frequencies. It is commonly used for comparing values across different categories and is effective in highlighting trends over time when categories follow a specific order.

Horizontal Bar Graph

A horizontal bar graph displays bars horizontally, with categories usually listed along the vertical axis and values displayed along the horizontal axis. This format is especially useful when category names are long or there are many categories, as it provides a clearer, more readable layout while still effectively communicating differences in data.

Data Visualization

Data visualization is the practice of representing data in a graphical or pictorial format. It enables easier interpretation and analysis of the information by converting complex data sets into more accessible and understandable visual forms. Effective visualizations help in identifying patterns, trends, and outliers, facilitating better decision-making.

Transcript

00:01 Well, this question asks us to draw vertical and horizontal bar graphs for the sales data of five different fast food restaurants.

00:13 They are when this pizza hot, stop beef burger king and kentucky fried chicken.

00:17 And the sales numbers are mattered in billions of dollars.

00:23 So here, let's first move on to vertical barograph.

00:29 Well, in order to make the graphs look like, look vertical like these, we need the x axis to be the categories of five companies.

00:41 And i use abbreviation here.

00:45 For example, w is for wendy's and k is for kfc, kentucky fried chicken.

00:51 And y is a number of sales measured in billions of dollars.

01:01 There's one more thing to do as when the data given are not in order.

01:06 So we need to first rank them in order and then draw them using bar graphs to make clear a illustration.

01:16 So the lowest number of sales are wendy's company and the highest numbers of sales are kfc.

01:24 And for example, wendy's has $8 .7 billion of sales.

01:29 So i draw them here.

01:33 And pizza hut has 9 .3, so i draw it here, slightly higher than with this.

01:39 And subway is 10, which is exactly this line here, also slightly higher than pizza hut.

01:45 And burger king has 12 .7, which is slightly higher than 12, which is the line here, approximately...
