Data Questions and Answers (Q&A)

Qualitative and Quantitative are two categories under which the various properties of items can be grouped into. In other words, the various properties of an item can be described either in a quantitative or qualitative way. Qualitative means the various qualities that can be attributed to a particular object. This talks in relation to the properties and the attributes that can be noticed in an object. These qualities cannot be measured or graded. For example, words that can be used to qualify something are; dark, beautiful, boring, wonderful, great, fascinating, useless.

Quantitative, on the other hand, refers to the observed properties of an object which can be measured. In other words, it refers to the quantity of an object which can be measured. Under quantitative, words that show the magnitude of an object is used. For example, words that can be used to quantify something are large, big, small, short, far, light, near, heavy, etc.

Data is used to create information. Have you ever looked at a table of figures, and not known what to do with them? That’s what data is without any kind of assessment or extrapolation. When all you have is a set of data, it doesn't usually mean much. Let’s say that out of 100 people, 20 of them prefer Body Wash A. The other 80 ranked Body Wash A dead last. That’s the data. The information is the “why do I care?” and the “so what?” that comes from the data.

For this set of data, information that comes from that would be that Body Wash A is doing badly in sales. As for why, that comes down to ingredients, scents, etc.

The hierarchical database seems more simple than the relational database, as it employs the logical parent-child relationship. A relational database, on the other hand, includes the use of tables to keep records in the form of table fields. In addition, a unique key is required for each record. A hierarchical database happens to be the processor for all other databases, and it has been in existence before the discovery of the relational database.

A category of data is referred to as "segments" in the hierarchical database, while a category of data is referred to as "fields" in a relational database. In a hierarchical database, every child segment inherits its parent's properties; while in the relational database, there are no data levels and no scenario of inheritance. A child is linked to its parent in the hierarchical database, and the segments are linked explicitly; while foreign keys and primary keys are used to link tables in the relational database in an explicit manner.

Ungrouped data is also referred to as raw data. When you conduct research or experiment, the uncategorized information you have at first is termed ungrouped data. This is the data you first gather. Ungrouped data is accessible for many people to understand.

Also, if the sample size of the group is small, it can be easy to calculate mean, mode, and median from ungrouped data. A grouped data is simply data that has been organized into categories or groups. Grouped data can be classified into groups and tables or chart can be created to represent the data. Histograms and frequency tables are often used to represent and interpret grouped data.

PTSD has been around since war began, and it is often associated with the trauma that soldiers had experienced in battles. However, it could also be apart of other problems that cause injury. PTSD stands for post-traumatic stress disorder. Another disorder similar to PTSD is called ASD, and it stands for acute stress disorder.

Even though the similarities include mainly the results by getting help, many symptoms are not experienced by both ASD and PTSD. Therefore, the symptoms have some variation when comparing PTSD and ASD. PTSD seems to have the symptoms of feeling that time is slowing down, more self-destructive activities, hypervigilance, and negative beliefs, whereas ASD does not have those symptoms. However, they have more nightmares than PTSD.

MB and GB are the short forms of Megabyte and Gigabyte. They are used as the basis for measurement, transmission, and storage of data. The first thing that needs to be explained is the word 'Byte'. A byte is a sequence of adjacent bits (binary digits) that can be operated on as a unit by a computer. The smallest unit for representing data on the computer is known as a bit, and each byte contains 8 bits. A kilobyte contains 1024 bytes, a megabyte contains 1024 kilobytes and a gigabyte contains 1024 megabytes.

Megabyte is used to measure the rate of data that will be transmitted and stored. A megabyte literally means one million bytes and it shows that one million bytes of data can be transmitted at once or has the total capacity that can store one million bytes. Gigabyte means one billion bytes, which means one billion bytes can be transmitted and stored at once.

RJ 45 and RJ 48 are two similar wirings or connectors, they use similar modular connectors, and it is not easy to identify the difference between them. Unlike if it comes to differentiating between RJ 11 and RJ 45 or RJ 48, that is actually easier to do. RJ stands for Registered Jack, and the major difference between these two entities in the discussion is their wiring. Both RJ 45 and RJ 48 use 8P8C modular plug with two pairs of the wires; one pair transmit data the other pair for receiving data.

The common RJ 45 uses the pins 1,2,3, and 6 to receive and transmit data. For RJ 48, the configuration can be used. A configuration can use the pins 1,2,4 and 5, and another configuration can use pin 1,2,7 and 8. The RJ 45 is popular in homes and offices as it is used majorly in a local area network where the network element's distance is short. The RJ 48 is used mostly in T1 data lines and other applications where the wires extend to long-distance, and it's exposed to the environment.

In programming languages, different data used are represented in various ways. Char and Varchar are two types of data representation in programming languages. 'Char' simply means character, while Varchar means Variable character. Char simply means a fixed-length character, and it is used to represent and store characters that are not Unicode. Varchar, on the other hand, is the short form variable character. It is a variable length character which can be used to represent any kind of character of different length.

However, there is a limit to the number of variables it can store. What determines the maximum number of the varchar field depends solely on the field length declared during the operation. However, what determines the maximum number of characters used for the operation depends on the total size of the column you declare while forming the table. Char and Varchar use different kinds of memory, Char uses static memory, while Varcha uses dynamic memory.
