Why a focus group?
Focus groups are an immensely powerful tool for exploring in detail how people think and feel. Unlike questionnaires and surveys, a focus group gives people time to reflect very deeply, and the confidence to express opinions honestly. Focus groups give the researcher time to present complex scenarios, and to probe more deeply into people’s thoughts and feelings.
However, focus groups can only provide qualitative data from a very small sample of people - never more than 10 per group. You should always check that the opinions of your focus group participants reflect those of the wider audience they represent by also using other quantitative methods, such as surveys or questionnaires.
What is a focus group?
A focus group is a discussion involving 6 to 10 people; lasting between 45 to 120 minutes. The people taking part have been recruited in advance and were selected because they share certain characteristics relevant to the research objectives e.g. they are all parents with children below the age of 12; who live in Greater London; and have never visited a science festival before.
The focus group is chaired by a moderator, who makes sure that everyone has an equal opportunity to contribute, and is based around a set of pre-designed questions. The session is digitally recorded for later analysis. The participants may also be asked to record their opinions and feelings through writing, drawing, selecting images etc.
But before you decide on focus groups
Focus groups are costly even if you do the recruitment yourself. You will probably have to pay participants a cash incentive; otherwise they will not turn-up. After all, you are asking people to give up quite a lot of their precious leisure time. Using a professional recruiter adds additional expense but saves you an enormous amount of hassle.
You will need at least one focus group for each audience group - combining very different types of people into one group just does not work. And each focus group generates a lot of data which will take a considerable amount of time to analyse. See How to analyse data from open-ended questions for details.
What you will need
- 6 to 10 participants per group (never more than 10). Recruited using a specially designed selection questionnaire
- A suitable room: quiet, minimal distractions, comfortable seating around a table so people can write, draw, look through pictures
- Two digital recorders plus spare batteries (just in case)
- A moderator to chair the discussion – keeping it on track and to time; ensure everyone gets chance to contribute, and nobody dominates the conversation
- A single silent observer who can also help guide people to the room, the toilets, pick-up late comers, deal with unforeseen events and taking notes.
- A ‘topic guide’ of 6 to 8 pre-designed questions
- Stimulus material to aid the discussion – picture, prompt card, model etc
- Basic refreshments – tea, coffee, water, biscuits, fresh fruit etc. Remember to provide vegan / gluten free options and check for allergies
- Incentives for attending –paid after people have attended the focus group
It is also possible to run focus groups via Zoom, Teams or Google Meets. In these cases you can offer a slightly lower incentive for participants and will not need to pay for refreshments. However, the quality of discussion is never as good as with an in-person focus group.
Recruiting participants
A focus group is not a town hall meeting where anyone can turn up. The success of your focus group depends on the quality of your recruitment process. It is vital that the people who are invited genuinely represent the audience you are researching.
Participants should be selected on the basis that they have certain characteristics in common. For example; they are all secondary school science teachers with at least 3 years’ experience; have taken students on at least one trip to a science centre within the past 5 years; and work in a school no more than 2 hours journey time from the science centre.
You, or the recruiter you employ, need to draw up a ‘screener questionnaire’ that ensures the people you ask to attend meet the required characteristics.
It is important you avoid selecting anyone who has a great deal more knowledge of the topic than the other participants. For example, if you are running a focus group with parents about a planetarium show, you would need to avoid selecting anyone with a degree in astrophysics. Otherwise, everyone else will defer to that person.
Running the focus group
As the moderator you have four key roles:
- Keep the discussion on track
- Use the questions and activities to elicit thoughtful and honest answers from the group
- Ensure everyone gets a fair chance to comment – encourage the more reticent members to contribute, and tactfully persuade the more talkative ones to give others a chance
- Keep to time – the session must finish at the agreed time
At the start of the session ask everyone to briefly introduce themselves. Take a note of their names so you can direct questions at specific people.
In a brief and friendly manner describe the ‘rules of engagement’.
- You will be recording the session but only you / the person analysing the data will ever to listen to it. All comments will be anonymised, no names will be used in the report. The recording will be deleted once the data has been analysed
- People don’t have to take turns or put their hands-up. But please only one person speaking at a time otherwise the recording is impossible to decipher
- Fine for people to disagree with each other but they must do so respectfully
- Fine for people to be critical - explicitly state that you won’t be offended
The aim is to get participants talking to each other rather than to you. The real value of a focus group is that people hear other’s comments and are confident to express their own ideas. As moderator you should only be speaking occasionally to add new questions, introduce a new activity, probe for clarification, and ensure everyone gets a fair hearing.
Topic guide
This is a list of questions you prepare in advance of the focus group. For a typical 90-minute focus group you will be able to ask around 8 to 10 main questions plus some additional probing questions in case people need further prompting. Have all the questions printed on one side of A4, so that you can glance at them during the discussion.
As moderator you will guide participants through the questions but the order in which these are covered will vary, depending on the ebb and flow of the discussion. Often people will jump ahead and anticipate a question. At other times they will loop back and talk about an issue that has already been covered.
Stimulus materials & activities
Providing participants with a rich variety of visual material, and different ways to express their opinions will help get the most out of the focus group.
If you are researching people’s response to an exhibition, or an online resource, you should give people a chance to look around it first, and have images / screen grabs to show during the discussion.
If you are researching people’s response to a live event you might want to arrange for participants to see a performance, watch a video of the event, or at least try out some of the component activities.
There are many examples of focus group activities which participants can be asked to complete individually, in pairs, or as a whole group. Depending on the aims of your research you could:
- Ask them to fill in speech and thought bubbles on cartoons
- Suggest endings to incomplete sentences
- Select images they feel best represent their thoughts, feelings, ideas etc
- Placing markers on a scale to indicate their opinion
Remember, when using visual methods, to ask participants to describe what they have created and why they have chosen the imagery they have. Their intended meaning will not be apparent from the images alone.
If you are running the focus group via video-link …
It is harder to get a free-flowing conversation and more difficult to show stimulus material. Online focus groups are harder to moderate, as turn-taking is more difficult to manage. There is also less rapport between participants as they have not had the opportunity to get to know each other.
During Zoom calls you can use apps like Jam Board - where participants paste up virtual post-it notes; comments via the chat function; votes and polls. However, these activities are not nearly as much fun as those you can run in a live focus group session.
