Introduction

How is the pandemic being tracked by graphs?

What are the different graphs related to COVID-19?

Recently, you may have come across various types of coronavirus graphs and data. Graphs and data help us to understand the health, social and economic consequences of this pandemic.

For our brain, processing images is much easier than processing text. The brain can process pictorial information 60,000 times faster than written information. Therefore, graphical representation of data is very important.

Types of Data

Discrete Data

  • It can only take certain values.
  • It can be counted.
  • It cannot be divided.
  • It can be graphed on a bar graph.
  • Example: number of dogs, number of books, number of students etc.

Discrete Data take certain values and can be graphed on bar graph

Continuous Data

  • It can take any value within a range.
  • It can be measured.
  • It can be divided.
  • It can be graphed on a histogram or a line graph.
  • Example: time, the weight of a dog, the height of the students etc.

Continuous Data can take any value within a range, it can graphed on a histogram or a line graph.


Introduction to Graphical Data & the rise of COVID-19 cases and deaths

Various charts and graphs can be used to visually display and analyze the graphical data. It helps us to quickly highlight the behaviour and relationship between data points which may contribute to better understanding and predictions. Depending on the type of data we may use a bar graph, histogram, line graph, heat map, Venn diagram, pie chart, etc.

Graphical Data & the rise of COVID-19 cases and deaths

What is flattening the curve? Flattening the curve is a strategy to slow down the spread of COVID-19. There was an exponential growth in the number of COVID-19 cases and deaths. Many countries announced lockdowns to prevent the spread of coronavirus from one person to another.

Types of graphical representations

Line graph

Line graphs are used mostly to show changes over time. For example, rise in COVID-19 cases, etc.

Line graphs are used mostly to show changes over time.

Bar graph

Bar graphs are used to compare data in categories. For example, number of deaths in different age groups etc.
