# ICT in Education/Student Activities/Mr. Tak Kean/Class M3/Group2/Group Activity/Assignment

Norin: It seems like on one has posted yet, so I think maybe I'll take the lead and be the first one to post about our assignment.
And if anyone see this and want to share your idea to the rest of the group please feel free to do so don't be shy.

## Assignment 2

Hor Norin >> Slide 15: Tell me the type of information can lead to the cost of lots of money and time. Slide 16: Elaborate more about different types of information and its characteristic as follow:
* Accessible Information: the information that easy to obtain and used. Ex: The result of the examination of the student.
* Accurate Information: the information that correct 80%-100% of the time and we can make use of to make proper decision. Ex: Information that came form the survey and the process of analysis.
* Complete Information: not too long but not too short information that contains all of what we want to know. Ex: The transcript of the student's academic performance.
* Economical Information: the information that related to the economic out come usually used for business activities. Ex: Stock market information.
* Flexible Information: general purpose information: Ex: Social rule and activities.
* Relevant Information: not sure about this one anyone can help me with this one?
* Reliable Information: "similar to complete and accurate information but used for specific decision making" is what I think. somebody can fill me in with this one.
* Secure Information: sensitive information that usually hide from certain people.
* Simple Information: normal information if I have to say.
* Timely Information: judging form the name imply this information must be important and need to get or deal with as quickly as possible.
* Verifiable Information: the information that can be used to verify something.
I've made the presentation slide too you guys can view it on my Wikiversity Page or tell me your Prezi account email so you can edit it later. That's all I have to share.
He Rotha>> well done Norin, now Navy is also discussing

The value of information depends on their usefulness in the decision making process. This value can be judged based on a set of features that can be identified in the information. They are as follows:
Accurate: Accurate information is error free. Errors could be occurred due to different reasons. If there is some problem in the knowledge required for the process, output (information) may have errors. At the same time, if input (data) contains some errors, the output will not be accurate. This is known as garbage in garbage out (GIGO). Inaccurate information is not error free. ភាពត្រឹមត្រូវ: ពត៌មានដែលត្រឹមត្រូវ គឺគ្មានកំហុស។ កំហុសអាចកើតមានឡើងច្រើនណាស់ ជួនកាលយើង Apply knowledge ទៅក្នុង Process ខុស, ក៏អាចធ្វើអោយលទ្ធផលរបស់យើងចេញមកខុស។ ពេលខ្លះ ការបញ្ចូលទិន្នន័យខុស ក៏អាចធ្វើអោយមានកំហុសពេលចេញលទ្ធផលមកផងដែរ។
Complete: Complete information contains all the important facts to make clear decisions. For example, an investment report may present all possible benefits and profits without details of cost that will be required. Complete information ផ្ទុករាល់ពត៌មានដែលសំខាន់ ដើម្បីអោយយើងដឹងច្បាស់។ ឧទាហរណ៍ របាយការណ៍មួយគ្រាន់តែនិយាយពីអត្ថប្រយោជន៍ និងអ្វីដែលចំណេញ មិនបាននិយាយពីលុយបានពីការចំណេញ ដូច្នេះវាមិនមែនជា Complete Information ទេ។ លុយបានពីការចំណេញ គឺជាអ្វីដែលសំខាន់។
Economical: Information should also be relatively economical. Decision makers must always balance the value of information with the cost of producing it. For example, if collecting the data takes lots of resources and time, it is not economical. សេដ្ឋកិច្ច: ពត៌មានគួរតែដឹងពីសេដ្ឋកិច្ច ឬការចំណាយ ដោយសន្សំសំចៃ។ អ្នកធ្វើការសម្រេចចិត្ត តែងតែគិតពីតម្លៃនៃការចំណាយដើម្បីទទួលពត៌មាន។ ឧទាហរណ៍ ការចំណាយពេល និងធនធានច្រើនក្នុងការប្រមូលទិន្នន័យដើម្បីទទួលបានពត៌មាន គឺមិនហៅថាការសន្សំសំចៃទេ។
Flexible: Flexible information can be used for a variety of purposes. For example, Information on how much inventory is on hand for a particular part can be for - a sales representative to determine the sales plan - a production manager to identify possible constraints for the production - a financial executive to calculate the current assets figures of inventory អាចបត់បែនបាន: ពត៌មានត្រូវតែអាចបន់បែនបាន តាមគោលបំណង។ ឧទាហរណ៍ នៅក្នុង Inventory មួយ ពត៌មានអាចអោយដឹងពីការលក់ ពីចំនួនផលិតផល តម្លៃផ្សេងៗ
Reliable: Reliability of information describes the correctness of the information. If there are any problems with respect to correctness of data, it will definitely affect the reliability of information. For example, if the reliability of data collection method is poor, it will directly affect the information that will be produced. For example, prediction of prices based on rumors (not past variance information), is not reliable.
Relevant: The relevance of information is determined based on the usefulness of information with respect to the decision making process. For example (E.g.A),, a drop in timber prices cannot be used to predict the price fluctuation in computers. តម្លៃឡើងចុះនៃឈើ មិនទាក់ទងតម្លៃឡើងចុះនៃComputerទេ
Simple: Simplicity in the representation of information is also a very useful feature utilized to improve the usability of information in the decision making process. Too many information could affect the simplicity in the presentation. Therefore it is better to provide interactive customization to determine simplicity. Providing too many information is known as information overloading.
Timeliness: Decisions should be made at the right time to achieve effectiveness. Timely information refers to providing information at the right time. For example, if you can get to know today’s weather forecast before you leave home, you can decide whether to bring an umbrella or not.
Verifiable: If it is possible to confirm the reliability of the information about its correctness (validate), it becomes verifiable Information. If you are not sure about a particular information (say foreign news) heard from a radio channel, you can search about it using Internet. ការផ្ទៀងផ្ទាត់
Accessible: Accurate information plays a major roll in the decision making process of any organization. Therefore it is essential to be able to access the Correct/ relevant information by authorized personnel at the right time to meet their needs.
Secure: the value of information could be lost due to issues such as unauthorized user access or intentionally damaging its existence. Therefore, it is important to makesteps to protect valuable data and information. For example, use of passwords to protect data and information.
It is important to note that the values of these quality attributes may vary from one piece of information to another. It affects their usefulness in the decision making process. For example, at the Stock Exchange, information about market forecast may not be very accurate but if the timeliness is poor, the total value of information will be very poor.
