Analysing Data
From looking at the .csv file below, you will have some time to analyse and draw out as much information and identify what you could present from this data to the group.

Factors that effect the Quality of Data
Often when collecting data, there are errors that can occur in the collection of data that are beyond the control of the collectors - these are referred to as Sources of Error.
The four principal sources of error are (as identified by the ABS (Australian Bureau of Statistics):
There are quality management processes to reduce error as much as possible.
The four principal sources of error are (as identified by the ABS (Australian Bureau of Statistics):
- Respondent error - when the person who fills out the survey, misunderstands the question and includes false data
- Processing Error - manual or automatic data entry errors
- Partial Response - when person filling out survey only completes part of the survey
- Undercount - when not all of the respondents to the survey have completed the survey due to a variety of reasons.
There are quality management processes to reduce error as much as possible.
2. Match the above with the following factors that affect the quality of data, and give examples of each:
a) relevance
b) accuracy
c) bias
d) reliability
a) relevance
b) accuracy
c) bias
d) reliability
Now that we have looked at data, collection of data and sources of data, it may seem like an obvious question - but why is it important for data that you are inputting into a computer to be free of errors?
What could happen if the data is inaccurate or irrelevant?
Think about a huge website like Wikipedia that provides information to people across the globe. Why are the following important when inputting data into a Wikipedia? (Pages 9-12 will help you answer these questions.)
Write these in your books:

Write these in your books:
- Relevance or Suitability of data - in terms of format. For example, for a company that hold employee wages - using a numerical format rather than string is more effective in performing calculations. 40 instead of 'forty'
- Reliability of data
- Accuracy of data
- Timeliness of data
- Freedom of bias of data
Privacy of Data and Consent Forms

Along with collecting Data there is a lot of Privacy and Ethical concerns with what the data will be used for.
Answer the following questions in a word document:
1. What are ways you can keep peoples information safe? Think of 2 different ways.
2. What is a consent form? Why is it important to provide when collecting information or data?
3. Find two examples of consent forms online and outline the key important factors/information to include on a consent form.
4. Create a consent form for collecting information about 1 of the following scenarios:
- You are a photographer, taking photos for a school website.
- You are a doctor collecting patient information.
- You are an employer collecting informaton on an employee.
- You are researching the affects of social media on day to day human interactions.
