  1. Application of Number portfolios A student guide To completing Level 1 & 2 portfolios

  2. What’s involved? • Design a project outline. An explanation of what your project is designed to show. Generally the project will be designed to compare or explore the information provided by two lots of figures. • Get 2 data sets.* These are two (or more) sets of figures (made up of at least 12 items for Level 1 or 20 items for Level 2) which will produce the information required for your project. • Make a few calculations. These arethe ‘sums’ which are used to illustrate the point orpurpose of your project. • Write a conclusion. A brief summaryshowing the conclusions drawn from the calculationsin two different ways, ie using text and diagram. • * DATA EXAMPLES • Weights and sizes • Costs of things • Speeds and distance • Height, length, capacity • Age, gender, weight • Times and timetables • Ranges of activity • Performance measures

  3. What’s your topic? • The project can be on just about any topic or interest such as comparing colleagues’ ages, qualifications, height or gender - which can usually be quickly obtained - with the same type of information collected elsewhere or at another time. National figures like these, with diagrams, for your use are included at the end of this presentation

  4. Example of successful project outlines The coffee shop I work in is being refurbished. The project I am undertaking is to see what type of customer is using our shop by recording their gender, their approximate time at the table and amount they spend. I will do this on three days and record my findings. I will then produce three diagrams to illustrate my results and, using a variety of calculations, show the trends for each of the days and compare them. I will write a conclusion which will help us decide on the new décor. My team members use different forms of transport to get to work and some travel long distances. I am going to survey 15 colleagues and find out how they come to work and what sort of distances they have to travel. I thought of splitting my information into two, looking at age or gender differences but I’ve decided to compare my data with national figures.

  5. Minimum datasets required for projects

  6. You need 1 diagram to go with one of your datasets Examples of acceptable diagrams Pie chart Bar Chart

  7. Project example 1 John Forbes Application of Number L2 Project outline I intend to test 12 male and 12 female members of our gym aged between 20-29 years old at Central Fitness, Birmingham. I will be collecting data on upper body strength and endurance with a press up test. Their scores will be compared against the ACSM (American College of Sports Medicine) norms for both gender and age. As John has done here, you can produce or source the 2 datasets yourself. They could be from a random sample, a short questionnaire or figures based on your own activity, experience and knowledge. Publications, company records and statistics, newspapers and the internet are other sources. John’s conclusions from this project are on a later slide

  8. Project example 2 John has used records from his work in a gym as data. He has measured the number of press-ups managed by 12 males and 12 females and entered them into tables as the two data sources. He has also generated a pie chart from one of the tables. Most students have information like this they can generate quickly in the workplace.

  9. How to write up calculations Explain everything you do and why you’re doing it as if you are writing for a beginner. Use your own words… 680 680

  10. Doing the sums L1 & L2 • Addition. Add at least two lists of values showing any carrying over that you do. • Subtraction. While doing your calculations make sure you do a couple of subtraction sums. • Range. Demonstrate a range between two numbers. (Highest value subtracted from the lowest). • Mean (Average). Work out a couple of averages. (Add a list of numbers together and divide the total by the number of values in the list). • Percentage. Find some percentages among your figures. (For example, each value in a list is a certain percentage of the total or value #1 is 30% greater than value #2 etc) • Convert. Work with and convert (showing your method) betweenpercentages, fractions and decimals. 25% = ¼ = 0.25 MUST DO Write out, and work out, some calculations by hand and check the results with a calculator

  11. Doing the sums L2 only 98 87 66 66 44 37 31 22 19 19 19 3 2 • Median. Mid-point in a descending (or ascending) list of values. (For lists with an even number of values, add middle two values and divide by 2). • Mode. Value that appears most frequently in a list. • Formula. Use a couple of formulain your calculations such as: Area = L x W Volume = L x W x H Average = Average speed = Sum of terms Number of terms MUST DO State the level of accuracy you are using ie. “I rounded down the total to 2 decimal places” Total distance Total time

  12. Area and volume

  13. Coming to a conclusion • Select at least 2 ways to present your findings • Present your findings clearly using a chart, graph or diagram and describe your methods • Describe what your results tell you and how they meet your purposes

  14. Example of project conclusion As I had predicted and can be seen from the mean value, the male participants (30) managed more press-ups compared to the females (18). It can also been seen from the percentages and the pie charts that the male group had a higher proportion of participants within the ‘Excellent’ (33%) and ‘Desirable’ (33%) range, compared to the female group who achieved 25% and 17% respectively. The males had a wider range (21) of total press-ups achievedcompared to the range of 19 from the female group. This isa difference of only 2 between the two groups and is thereforeconsidered insignificant. From these results it can be claimed that the male populationat Central Fitness, Birmingham have higher levels of upperbody strength and endurance compared to their femalecounterparts. In this example John has drawn some interesting comparisons between male and female performance in press-ups. Project conclusions are clearly related to his project outline.

  17. Information for tutors 3 Useful for a survey among work colleagues. Circulate questionnaire requesting highest level of qualification or gender & job title and make comparison with national picture.
