Understanding Research Concepts

A theory is different from a hypothesis because

• a theory has been proved to be 100% true.

• a theory has a lot of supporting evidence.

• a theory is less certain than a hypothesis.

• when a theory is widely accepted, it becomes a hypothesis.

Qualitative research

• yields high-quality data.

• does not use people’s opinions and feelings.

• may often use surveys and interviews.

• always uses closed questions.

Data is related to information in that

• information is processed from data.

• data is processed from information.

• data is more important than information.

• data is more accurate than information.

A closed question

• is asked during a confidential interview.

• tests whether the respondent is telling the truth.

• has a limited range of possible replies.

• does not get an answer.

Ajax Market Research interviews 1000 elderly people about whether pensions should be increased or not. The collected data might be

• reliable because elderly people know about pensions.

• biased because the elderly people have a vested interest.

• reliable because it’s primary data.

• unreliable because it’s such a small sample size.

A differential data backup

• saves all data.

• is slower than a full backup.

• saves data that has been created or changed since the last backup.

• is any form of backup that is different to a full backup.

A good backup strategy

• specifies that backups are stored offsite.

• ensures backups are stored in a fireproof safe.

• should be implemented as soon as disaster strikes.

• must include cloud storage.

A firewall is used to

• filter out dangerous information coming into a computer or network.

• encrypt documents.

• prevent viruses entering a network.

• check the accuracy of incoming data.

The best choice of chart to compare data trends over time is a

• pie chart.

• scatter chart.

• nautical chart.

• line graph.

A pie chart is appropriate when

• you have at least ten categories.

• your data is sorted from largest to smallest.

• you need to show parts that total 100 percent.

• you need a colorful graphic for a report title page.
