# Find out which supermarket the public prefers.

Extracts from this document...

Introduction

Samantha Stanley

Maths – Supermarket shopping

Coursework

In this investigation I am going to find out which supermarket the public prefers. I shall create a questionnaire / survey to find out which supermarket is the favourite.

I shall gather continuous data by asking questions such as: “how long does your journey take?”. I shall gather discrete data by asking questions such as “what is your favourite supermarket?”.

In my questionnaire / survey my questions will be aimed at the adult population. This is because adults usually do most of the shopping.

I used cumulative frequency diagrams to show me what the interquartile range is like. Using discrete questions to find discrete data on to which I am able to use this data to form my graphs.

Questionnaire

1) Where do you prefer to do your food shopping?

Morrisons

Asda

Tesco

Sainsburys

Somerfield

Other

2) Why do you shop there?

Recommended

Cheap

Quality

Local

3)

Middle

220

220

40

3120

Mean = Total (Mid Point x Frequency)

Total Frequency

= 3120

40                    = £78 is the average amount of money spent.

The above bar chart shows the discrete data using the question “Where do you prefer to do your food shopping?”

The bar chart shows that most people I have asked in my questionnaire / survey prefer to do their food shopping at Asda.

I am now going to draw a cumulative frequency table. Using the results from the following table, I will be able to produce a cumulative frequency graph, which will enable me to see how much money people spend on average on shopping.

 Group Tally Frequency Cumulative frequency £0 - £40 0 0 £40.01 – 80 l l 2 2 £80.01 - £120 l l l 3 5 £120.01 - £160 l l l l   l l l l     l l l l 15 20 £160.01 - £200 l l l l   l l l l l l l l   l l l l 20 40 £200 > 0 40

Conclusion

These prices are probably why a lot of people chose to shop at Morrisons.

Although Morrisons is cheaper on prices, it may not be as good quality.

The public in which I have asked have chosen Asda to be there overall favourite supermarket. This may be because it has good quality, prices are fairly cheap, or it is the local supermarket.

The further away the supermarket is, the more money most people are more likely to spend. This may be because they do there big shops there as they probably not visit that supermarket as often.

Personally I have enjoyed doing this coursework. I enjoyed learning more about cumulative frequency diagrams and using discrete questions to find discrete data on to which I am able to use this data to form my graphs.
