Data Input Data Collection and Validation

How does a simulation differ from a simple data model?

• A simulation does not use real-life scenarios.

• A simulation is a computer program that uses formulae to predict outcomes.

• A simulation is a list of raw facts and figures.

• A simulation is a predefined document for collecting data.

What is a data model?

• A type of spreadsheet used for calculations

• A digital representation of a real-life scenario broken down into individual attributes

• A list of raw facts and figures

• A predefined document used to capture data

Which field is mentioned as using simulations for safer training of pilots and doctors?

• Gaming

• Training

• Tourism

• Education

What does the term "data requirements" refer to?

• A list of software needed for a project

• A list of data items required to produce an accurate model or simulation of a real-life scenario

• A list of hardware needed for a project

• A predefined document used to capture data

What is a linear search?

• A search that compares each element in a sequence until the desired element is found

• A search that uses binary division

• A search that only works with sorted data

• A search that skips every other element

What is the purpose of a data-capture form?

• To organize data in rows and columns

• To collect appropriate data for a specific purpose

• To perform calculations on data

• To predict outcomes using formulae

What does AR stand for in the context of simulations?

• Advanced Reality

• Augmented Reality

• Artificial Reality

• Assisted Reality

Why is validation important in data entry?

• It increases the speed of data processing.

• It reduces the chance of errors being made when data is entered into a computer system.

• It formats the data into rows and columns.

• It captures data for specific purposes.

Why might VR and AR be beneficial for tourism?

• They make travel faster.

• They allow travellers to explore locations before visiting them in real life.

• They reduce travel costs.

• They improve flight safety.

What is a primary key in a database?

• A field that allows duplicate values

• A field that uniquely identifies each record

• A field that stores the most data

• A field that only contains numerical data
