Tools Of Data Collection That You Need To Know

How seriously do your organization take data collection? Data collection is a very important aspect of any business today. If you want to prove this, you need to compare two different businesses, the one that is keen to properly collect it is data and also the one that does not. You will at long last realize that the difference is extreme. So what data collection tools that your business or organization employs? There are many data collection tools that you can use. This article explores some of those tools.

Case studies

Case studiesA case study is of one of the most common techniques that are used in data collection. It involves in-depth study of a structure, a company or any other entity with the intention of coming out with particular information. The case study involves a combination of quantitative and qualitative data collection techniques. Most people who participate in making use of this tool normally begin analysing quantitative data first before moving to qualitative. The qualitative part is used to derive meaning from the data that is collected.

Checklists

Checklists are normally meant to evaluate a person’s performance or even artifact. They sometimes can be as simple as a register when people are marked either present or absent. Checklists are also very important tools of data collection as they can be used to evaluate database, the use of library space, virtual IM service, or for the structuring of observation instruction sessions.

Interviews

Interviews are widely used all over the globe. They can be carried out in two different ways. First, it can be between two individuals, or it can involve a particular company and a large group of people. The data can be recorded using tapes, or they can even be written down. In an interview, it is normally assumed that there are a questioner and an interviewee. The main purpose of the interview is to question the interviewee about the matter of interest.

Observation

Case studiesObservation is common to nearly everybody. People have always used this tool to collect data in many occasions. The good thing with this method is that it can be done whether the subject is aware that you are observing them or not. Depending on your project, observation can be a simple and easy technique of data collection as it is very flexible. There are three major  types of observations;

  1. Descriptive observation
  2. Inferential observations
  3. Evaluative observation

Various Uses Of High End Drones

Drone technology is ones of the greatest breakthroughs in human life. They are versatile as much as most people associate them with cinematography. The best drones are expensive but very useful. As a matter of fact, the expensive high-end drones are by far the best options any serious buyer has.This article will highlight the various uses of such drones which will further assist in deciding.

Various uses of drones

Cinematography

DronesWell, the movie and documentary makers have a reason to smile. These small crafts have made their life way easier and more exploring. Making some footages and shots could risk a human life but with drone technology directors can include them without a risk to anyone. More so, the documentary makers who need to captures the ‘no go zones’ can now bring such to people’s screens. The crafts are fitted with high-quality cameras that can either record and save or record and transmit live.

Wildlife management

Various bodies dealing with conservation of wildlife can use a drone to monitor animal and carry out other related tasks like animal population count. One advantage of a drone is that it’s small and does not make noise to disturb animals. Their surveillance can as well be sued to hunt poachers who terrorize animals and course threat to their existence. However, the control unit needs to trail closer to the drone to avoid incidences of a failure due to wind or battery issues.

Farm management

DronesSince the invention of the drone, farm owners have been eying this technology and wondering how they can incorporate it. Thanks to critical thinkers, drones may not water the farm or spray the insecticide but can locate where such needs are dire. They can also identify the position of stray animals or the general situation of the animal farm. Farmers have, therefore, got a reason to use this technology on their farms.

Disaster search and rescue

Ever thought of a chopper hovering around a small area where people are trapped? It can be a bit difficult for the big machine. However, the small craft can maneuver near the rumbles and give a real time feedback of the situation. Drone have assisted in locating people in a faster and accurate way during rescue missions.

This and the other highlighted uses are thus a good reason to buy a high-end drone today. Make the best choice now.

Techniques Used In Searching Electronic Documents

This involves searching of electronic data contained in the computer for the various purposes. The process of searching data on a computer is different from searching a document within a file or in a cabinet. The term search is therefore very broad.

It is very easy when you are looking for a file within a cabinet since you can touch, see, smell or even feel it. However, the searching of electronic documents from a computer involves searching for documents that you cannot smell, touch or feel but you can still see the document on the computer’s screen either in texts or number forms. The various numbers seen on the screen are a combination of zeros and one commonly known as binaries.

Electronic DocumentsIn general, computers do not store data in Spanish, English or German but they store data in binary form. Computer users usually employ different names when saving their files. This means that a detailed search is required when looking for documents in a computer. Further techniques and knowledge will be necessary when retrieving data on a computer. “Keyword” search is the starting point when you are searching for any data.

Keyword

When conducting computer searches, you do not have to an emphasis on the names related to the documents. You should rather concentrate on a string of data or an operative word which might lead you to the relevant document which contains the terms you are searching.

Using “keywords” is critical to computer searches. The ability to formulate the appropriate search terminology or keywords is very critical. Computers will only respond to the questions asked during the searching process.

Synonym search

This kind of search returns to the extended patterns associated with the search word. For instance, when you search for a car, the results might turn to cats or catlike.

Fuzzy searchElectronic Documents

This help in finding the search word even when it is misspelled. For instance, the search for a word like “house” will return to the search result for “house.” This helps in those circumstances when you have some issues in spelling the words correctly.

Noise words

Most of the advanced and specialized search applications such as forensic and Ediscovery provides you with an opportunity of excluding the “noise words” during the search. Eliminating the noise words helps to save the computer resources and time. Example of noise words are:e.g., was, e.t.c

Concept search

This involves the use of the search questions in identifying a group of documents which have a similar thread or subject matter. The approach is important in locating some documents which have more or less similar content.
