Unit 3 - Managing data (Grade 7)

1. A digital data representation of a real-life scenario; the scenario is broken down into individual attributes, which are represented as data items.

(a)  

A model that is interactive, using formulae to change the model in real-time. (a)   can be used to predict outcomes and are particularly useful in training and experiments.

Raw facts and figures.

(a)  

An application that uses rows and columns to organise data and carry out calculations using that data.

(a)  

A way of investigating a scenario using a data model, where one or more pieces of data are adjusted to see how it affects other parts of the model. (a)   helps you understand how different changes can impact the results

simplified versions of something in real-life that helps us understand how it works.

(a)  

the ability to grow or change easily when you need more resources or when things get bigger.

(a)  

how close something is to the real thing or the correct answer.

(a)  

Understanding what (a)   is needed is crucial (very important) for running the model effectively.

The (a)   of a model refers to how precise its predictions are compared to actual data.
