name the information categories used by individuals?
communication, education and training, entertainment, planning, financial, research and location dependant.
what are the steps of data analysis?
identify the need
define the scope
identify potential sources
source and select information
select the most appropriate tools
process and analyse data
record and store information
share results
2. identify the scope
in this stage the restrictions of the project are defined. scope includes factors such as budget, content, detail, timescales and further constraints.
identify the need
objectives are set for what the data analysis will hope to achieve. the aims must be clear and well defined.
3. identify potential sources
must identify a wide range of sources for the potential information, ensuring it is unbiased and covers the objectives.
4. source and select information
the stage where information is gathered and the best is selected. the gathering process uses existing information; for example sales figures.
the selection process is intended to exclude any information that may not be suitable.
5. select the most appropriate tools
there are many different data analysis tools that can be used as part of this sequence. in this stage the most appropriate tool for the project is selected.
regression analysis- this is the determining of relationships.
trend analysis- this shows patterns over time.
6. process and analyse data
the stage at which the data that has been collected is entered into software and analysed. for example data is entered into a spreadsheet and a graph produced to show the information visually.
7. record and store information
the stage at which a report into the findings is written. this includes all of the results that have been processed
8. share results
the final stage of the process is where the results are published so that stakeholders may inspect them. this may be in the form of a written, printed report, or could be pages on a website.
data tables:
databases are often split into tables which make sit easier to update, view and manipulate data.
they allow for the most simple form of pattern discovery and are a good method of speedy, short-term data analysis.
what are the disadvantages of data tables?
they can only show current format of data and cannot show change or trends over time.
visualisation of data is a way of representing data in a way that makes it easier to understand and interpret
visualisation of data:
example is producing a chart or graph.
it makes it easier for an audience to see trends and patterns. and it is easier to understand and its quicker to interpret.
trend and pattern identification: the process of identifying the trends and patterns in the data
trend and pattern identification allows trends and patterns to be viewed as a visual format e.g. a line graph of stock sales.
statistical analysis- to examine numerical data and highlightrelationships between different data elements.
regression analysis- discovering links between variables.
data cleaning:
ensures that any stored data is up-to-date and accurate, in accordance with the data protection act (2018).
it reduces the size of any data tables by removing redundant, incorrect or unnecessary data. it makes it easier to work with the data table and improves the data quality.
GIS/ Location Mapping:
geographic information systems are used to add geographic data to any analysis. for example courier services use it to see delays and delivery times in real-time.
what are the 2 types of information systems?
open and closed systems.
open information systems:
Can interact with other information systems to exchange data, even from different platforms.
Because it is open it it more at risk of data loss and/or hacking.
closed information systems:
Is private and cannot exchange data with other systems. Access is limited but is much more secure than an open system.
categories of information for organisations:
Knowledge management and creation
Management information system (MIS)
Marketing, promotion and sales
Finacial analyses and modelling
Contact management
Decision making
Internal and external communication
Big data
information categories for individuals:

Internal and external communication
Providing a communication medium to staff and/or customers
Decision making
Using available information to make decisions
Contact management
Managing contact between a business and the customer
Financial analyses and modelling
Analysing trends e.g. determining the top selling products of the year
Marketing, promotion and sales
Identifying patterns or trends in sales figures, so that certain products or areas can be targeted.
Management information system (MIS)
A system that provides an overview ok key information
Knowledge management and creation
Managing information across an organisation e.g. sharing information between different branches
Big data
Data that is too large or complex to be analysed using traditional mediums.
