Data Capture 01

Data capture is how computers collect information, from online forms to sensors. In this quiz you will explore methods, devices, and checks that keep data accurate.

(quiz starts below)

Fascinating Fact:

Data loggers can record readings over time, like temperature, light, or sound levels, without someone watching all the time.

In KS3 ICT, data capture is about choosing the best way to collect information and reduce mistakes. You might use forms, scanners, sensors, or manual entry, then apply checks like validation to keep the dataset reliable for analysis.

Key Terms

Input device: Hardware used to enter data into a computer, such as a keyboard, scanner, microphone, or barcode reader.
Verification: A method of checking that data has been entered correctly, such as double entry or comparing with the original source.
Sampling: Collecting data from part of a group to represent the whole, which can save time if the sample is fair.

Frequently Asked Questions (Click to see answers)

What does data capture mean in ICT?

In ICT, data capture means collecting data and entering it into a computer system. This can be done by people typing, by scanning, or by using sensors that gather readings automatically.

What is the difference between validation and verification?

Validation checks whether data is sensible and in the correct format, such as a range check for age. Verification checks whether the data was entered correctly, such as double entry to spot typos.

What is a data logger used for in data capture?

A data logger is used to collect sensor readings automatically, which helps when data needs to be gathered regularly. It is useful for experiments and monitoring conditions without manual recording.

1 .

The two methods of data capture are called .......

manual and automatic

manual and validated

paper and paperless

validated and verified

A barcode reader is an example of automatic data capture. Even though it requires a person to use the reader, the data from the barcode is read automatically. The only time it is done manually is if the reader is broken or the barcode is not clear enough for the reader to work

2 .

Which of these uses a manual method of data capture?

Bar-code reader

Filling in a questionnaire by hand

Supermarket laser scanner

Temperature sensor

If it involves writing it must be manual

3 .

Market researchers use questionnaires to get data .......

as the data needed might be hard to obtain automatically

as they can change the questions to suit the person

because it is more accurate

because it means they can meet people face to face

Market research requires data capture from people, so it has to be done manually

4 .

Questionnaires and data capture forms .......

always need someone to key-in the results by hand

are always paper based and have to be stored in boxes

can sometimes be made machine readable

have to be filled in completely or are not useful

Multi-choice answer sheets for exams are often scanned by optical mark recognition (OMR) hardware and software

5 .

Which uses an automatic method of data capture?

AutoDC

DFR

DocuR

MICR

A magnetic ink character recognition (MICR) device can read magnetic ink on documents

6 .

Which is not a feature of automatic data capture?

Can be used in locations dangerous for humans

It is usually faster than manual data capture

It usually requires constant human supervision

It usually requires extra hardware

The opposite is normally true, automatic data capture involves only the minimum possible human supervision which is why it is so useful. Imagine having to take a temperature reading every minute for 48 hours ... a datalogger with temperature sensor does not sleep or get bored and only requires human intervention at the start and end of the process

7 .

Data capture forms .......

need lots of graphics so people do not get bored

should ask for as much information as possible

should have a simple, easy to follow layout

should use the smallest size fonts to save paper

A simple and logical layout is very important

8 .

Data capture forms need a lot of thought being put into the design because .......

they make the information more reliable

they reduce misunderstandings when being completed

they make the information more accurate

All of the above

The person completing it could be confused and enter incorrect data, or enter data in the wrong place. Data from a poorly designed form could be both inaccurate and unreliable

9 .

Data capture forms need careful design .......

to make sure questions provide the required information

to make sure the right answers are given

to make the company look professional

to make the form look cool

The important part is to get the information required. If the wrong questions are asked, irrelevant data could be gathered and useful data could be missed

10 .

How can you stop people giving long answers?

Ask people to give short answers if possible

Ask simple questions

Only give a small space for answers

Use single character boxes for answers e.g. 'y/n'

Responses should be restricted whenever possible so questions need to be carefully designed to lead to a short answer. Giving a small space for answers can work but sometimes people then just write outside the boxes
