Flash Cards: Data Handling and Presentation

Data is a collection of facts, numbers, measures, or observations that convey information about specific things.

Data can be collected by conducting surveys or asking questions to a target group about their preferences or observations.

Data can be organised using tables or charts to make it easier to read and understand the information collected.

Frequency is the number of times a particular data point appears in a dataset.

A bar graph can be used to visually compare different categories of data, like students' favorite fruits.

Asking students about their favorite subjects and creating a list is an example of data collection.

Arranging data means organizing it in a specific order, such as ascending or descending, to analyze it easily.

To find the most popular item, list all options and count how many votes or preferences each option receives.

Comparative statements are used to compare two or more items based on their data, like 'more or less preferred.'

Collected data should be analyzed to draw conclusions or make decisions based on the findings.

A survey is a method of gathering information by asking a sample of people questions about their preferences or experiences.

The mode is the value that appears most frequently in a dataset.

A common mistake is not recording data accurately, leading to incorrect conclusions.

Data refers to raw facts, while information is data that has been processed or organized to make it meaningful.

Organising data helps in easily analyzing and interpreting it, leading to better understanding and decision-making.

A bar graph is a visual representation of data using bars of different heights to show the values of different categories.

You can show data comparatively using diagrams like bar graphs, pie charts, or tables.

A pie chart is a circular graph divided into slices to illustrate numerical proportions of different categories.

A data set is a collection of related pieces of information, often displayed in tables or charts for analysis.
