Use of Computers in Research

Computers have changed the ways in which scientific research is compiled and analyzed. Scientists, engineers and researchers alike are able to compile vast amounts of data and leave it to the computer to work through the data while focusing on another area of the research project. This creates research results with fewer errors and better-engineered products.

Complex Data Analysis

Computers used in scientific research have the ability to analyze data in ways and at speeds not possible with the human eye. They are able to analyze percentages of materials present in a variety of compounds from soil samples to chemicals and even the air you breathe. Additionally, computers used in this manner can determine trends in data samples. For example, computer analysis of data in research could determine the temperature at which certain chemical compounds break down or the percentages of improvement patients show when administered a certain medication.

Solving Mathematical Equations

Scientific research often requires that complex mathematical equations be solved in order to determine if data is valid or if a certain structure of molecules will remain stable. Computers are integral to this calculation process since scientists can write software programs specifically to provide answers to such questions. This removes the element of human error, which can cost research institutions millions of dollars in fixing a product that was created with even the smallest amount of flawed data.

Prediction Modeling

Scientists and researchers are able to use computer programs to model how data might manifest itself in the future. This ability is useful in predicting climate patterns, simulating how engineered products might perform in the field, predicting the erosion rate of beaches and anticipating the absorption rate of medications in the body. Scientists and engineers are then able to adjust building strategies or chemical compositions of products to ensure safe operation and consumption.

Computers Are Used in Business Management

Data Management

Data management activities form the foundation for many activities that businesses perform. Computers make it possible for companies to organize and manipulate massive amounts of information productively. Larger corporations may use multiple SQL Server databases to oversee data operations while smaller businesses might take advantage of the data manipulation features in applications such as Microsoft Access. Regardless of your business's size, you probably work with information and need to store it. Business websites also use database software to sell products and even give people the ability to join their sites. If you a have a website, you can set up data management software yourself or hire a company to manage it for you.

Office and Supply Management

Companies make money by buying and selling products at a profit, and computers help them manage inventory and supplies efficiently. Wal-Mart, for example, uses a sophisticated NeoVista inventory management software system that enables the company to keep products available in stores when people need them. Computers are also useful for helping smaller businesses track and manage basic supplies, such as printer paper, pencils and even cups for the water cooler.

People Management

Communicating with a coworker who is sitting in the next cubicle is rarely a problem, but coordinating and managing meetings where people reside in different states can be a challenge. Computer software enables businesses to conduct virtual meetings where people meet over the Internet and makes it possible for everyone in the business to view a common calendar. Some companies strive to increase productivity by monitoring the computers that people use. Monitoring enables companies to track billable hours and identify activities that may be unprofitable. If you do any kind of time tracking or meeting planning, scheduling and calendar software can help you.

Record Keeping and Accounting

When tax time arrives, you can be prepared by accessing financial records that you've kept during the year on a computer. Accounting software helps people manage money, create budgets, track sales and monitor resource usage. Products provide accounting solutions for businesses of all sizes. Look for accounting programs that can access the Web if members in your organization need to access and share accounting information from multiple locations. You’ll also find spreadsheet programs useful for doing everything from creating time sheets to managing payroll.

Computer-Based Learning

Computer-based learning is a term that can be used to describe virtually any kind of learning program using computers as a central staple. This approach to learning takes advantage of the interactive elements of computer software , along with the computer’s ability to present many different kinds of media. There are several potential advantages of computer-based learning programs, including the ability for people to learn from their homes and study without the assistance of an instructor.

Some people are opposed to computer-based learning because they feel it depersonalizes the classroom experience, and that it may lack the necessary flexibility to handle problems that students face during the learning process. Computer-based learning has been used as a tool in the midst of a more traditional classroom experience. It has also been used as a primary education method, especially in many online education programs.

The use of computers for learning has generally increased with the advancement of technology. The ability of computer hardware to process and present many different media types has allowed for more complex computer learning strategies . An example would be a training module that uses video along with text and audio files for lectures. Tests and exercises are often handled in an interactive manner, and sometimes they can almost be like games, depending on the style of the implementation.

Using Computers for analysis

Quantitative analysis with computers

When you are handling large amounts of data and need to store or to arrange data items efficiently, a computer based approach is invaluable. The ability of a computer to make repetitive calculations rapidly and accurately has revolutionised quantitative research and it would now seem rather out of keeping with normal practice to try to undertake such analysis by hand.
There are large numbers of computer programs that can assist with quantitative analysis.

Probably the most commonly used are Matlab, Excel and SPSS all of which are available on computers on the University network.

Computers and qualitative research

It is sometimes argued that computer programmes can distance the researcher from the data and thereby influence negatively the analysis and interpretation of meaning. Notwithstanding these criticisms, several good computer programmes exist that can help the researcher to manage large data sets and the processes of filing, storage, coding, retrieval and presentation of data. These Computer Aided Qualitative Data Analysis Software (CAQDAS) programmes can replace or support some of the manual tasks that qualitative researchers need to undertake. Tesch (1993) suggests that these programmes can help with the different approaches to qualitative research (language orientated, descriptive or interpretative and theory building) by assisting with:

• Storing, annotating and retrieving texts
• Finding words, phrases and segments of data
• Naming or labeling data
• Sorting and organising the data into manageable sections
• Identifying sections (known as units) of data
• Preparing diagrams and maps on screen
• Retrieving and extracting quotes.
