Lesson 1: Picture graphsData: FAQ
Frequently asked questions about data.
What is a picture graph?
A picture graph is a type of graph that uses pictures or symbols to represent data. For example, you might have a picture graph that shows how many apples, oranges, and bananas you have. Instead of using bars or lines, the graph might use pictures of the fruits to show the quantities.
What is a bar graph?
A bar graph is a type of graph that uses bars of different lengths to represent data. The lengths of the bars show the quantities or values of the data. Bar graphs are often used to compare different categories of data.
What is a line plot?
Line plots are a type of graph that display data as points above a number line, showing the frequency of each value
What's the most important thing to remember when making a graph?
We need to make sure that the graph is accurate and easy to understand. This means choosing the right type of graph, labeling everything clearly, and using the right scale.
Where are these types of graphs used in the real world?
We see these types of graphs all the time! Businesses might use them to track sales over time, scientists might use them to study changes in temperature, and sports teams might use them to compare player statistics.

So this data bar graph is used to measure temperature?(15 votes)
Yes, but not only for temperature. Graphs are also used for other things like representing how good a player is, or how many apples or bananas are there are. Graphs are used for so many things!(17 votes)
what is a data(2 votes)
In computing, data is information that has been translated into a form that is efficient for movement or processing. Relative to today's computers and transmission media, data is information converted into binary digital form. It is acceptable for data to be used as a singular subject or a plural subject. Raw data is a term used to describe data in its most basic digital format.
The concept of data in the context of computing has its roots in the work of Claude Shannon, an American mathematician known as the father of information theory. He ushered in binary digital concepts based on applying two-value Boolean logic to electronic circuits. Binary digit formats underlie the CPUs, semiconductor memories and disk drives, as well as many of the peripheral devices common in computing today. Early computer input for both control and data took the form of punch cards, followed by magnetic tape and the hard disk.
Early on, data's importance in business computing became apparent by the popularity of the terms "data processing" and "electronic data processing," which, for a time, came to encompass the full gamut of what is now known as information technology. Over the history of corporate computing, specialization occurred, and a distinct data profession emerged along with growth of corporate data processing.(1 vote)
