In the electrical industry, tables are often used to record test results or to compare performance data of electrical components, materials and machines. Have a look at the table below, relating to accidents reported to the Health and Safety Executive and answer the questions that follow.
1. How many categories of reported incidents are shown in the table?
2. In which year were there the most fatal injuries?
3. When were there the most near misses?
4. Has there been an increase or decrease in non-fatal injuries in the last 4 years?
5. Which year had the lowest number of fires/explosions?

Section B: Information displayed in charts Similar to the use of tables, charts provide a graphical and simplified view of what can sometimes represent a large amount of information, or data. Column Charts Using the data from the table in section A; Incidents reported under the Electricity Safety, Quality and Continuity Regulations, a column chart has been produced to compare the non-fatal accident data from year to year. This gives a pictorial view of how the number of non-fatal accidents changes from year to year. Column Chart: Non-Fatal Accidents; Electrical

Using the internet or catalogues select six different types of (power and hand) tools, suitable for an electrician to use for fixings. QUESTION 1 Create a spreadsheet to display your list of tools. (a) Add extra columns and find each of the following: a. Approximate price of the tools.
(b) In the space below draw a pie chart using the information in your spreadsheet regarding price of tools: a. Tools up to £30.00. b. Tools between £31.00 and £75.00.
b. What appropriate fixings the tools can be used for.
c. Tools over £75.00.
c. What material types and properties (e.g. brickwork) the tools can be used on.
Actual answers will vary depending upon figures selected by individual learners.
QUESTION 2
QUESTION 4
What conclusions can you draw from your pie chart?
Actual answers will vary depending upon figures
