1. Data search, collection, processing and analysis. Mahmood Arabi

2. Data searching There are two ways to search for data: • Either obtain the data from a secondary source such as the internet. • Or design an experiment or setup where you yourself can search for data.

3. How to data search In science there many types of experiments, however the method of recording of data has changed due to the advancement in technology. Equipment that is available today : • Sensors • Computers • Database Software

4. Sensors • With the combination of a computer and a data logging software, and sensors we are able to conduct our own searches in a quicker and more efficient manner. • Sensors for conducting experiments include : • Pressure sensors • Temperature sensors • Atmospheric sensors • Ph Sensor • Motion sensor • All these sensors can be used for data searching in the real world

5. Collecting Data • Using Appropiate software and the sensors anyone can collect data and store it on a piece of hardware. • The modern way of collecting data has become more accurate and efficient

6. Advantages and Disadvantages Advantages • Accurate • No human error • Can work 24/7 • More frequent readings Disadvantages • Technical problems can cause loss of readings • They can easily be set off

7. Social and Ethical issues Ethical issues • Reliability • Security Social issues • People can become too reliant on the equipment. • Environmentally friendly • Time efficient

8. Processing and Analyzing Data • The data available can be processed in many ways such as : • Graphs • Tables • Equations

9. Data processing • Computer data Processing is any process that uses a computer program to enter data and summarize, analyze or convert data into useful information • This includes : • Recording • Analyzing • Sorting, • Summarizing • Calculating • Disseminating • Storing
