What is the difference between attribute and variable?
An attribute describes something. A variable is something that can take on many values. An example in statistics for an attribute could be for a set of data the diameter. The attribute of the data could be the mean is 5 and standard deviation is 1/2. This describes the data. An example of a variable in statistics for the same set of data above is the diameter reading itself. The diameter will vary and is measured for each member of the population or sample, and may be 4.9, 5.1, 4.95, 5.05, etc. The value can vary on each part.
How do you the mode in a set of data?
The mode is the most common value in a set of data. A set of data may not have a mode (for example, if each value is listed once, then there is no mode since no one value is more common than another), or a set of data may have more than one mode (for example, if there are 3 different values that are each listed 5 times in a set of data, then each value is a mode). Example (no mode): {1, 2, 3, 4, 5} no mode Example (1 mode): {1, 1, 1, 2, 3, 4, 4, 5} mode is 1 Example (more than 1 mode): {1, 1, 1, 2, 3, 3, 4, 4, 4, 5} modes are 1 and 4 Example (more than 1 mode): {1, 1, 1, 2, 2, 2, 3, 3, 4, 4, 4, 5, 5, 5} modes are 1, 2, 4, 5
Would data set on ethnic groups be a qualitative variable?
Some variables in the data set might be qualitative, others might not. For example, if one were to sample newly arrived immigrants to Toronto, Canada and create a data set of information about them one could include both qualitative and quantitative data. One might measure each person's height which would be quantitative, and observe each person's eye colour, which would be qualitative.
What is Dependent Sampling method?
Data gathered in two different samples in such a way that there is a matching of the first sample data drawn and a corresponding data value in the second sample data. For example, compare two sample means, one for the first exam of the semester and the second for the second exam of the semester, match via the student taking each test.
What are some examples of data mining techniques?
Although there are a number of data mining techniques there are three that are most commonly used. These common techniques include decision trees, artificial neutral networks and the nearest-neighbour method. These techniques each analyze data in different ways.

What are the various file-accessing techniques in data management system?
Explain the various file-accessing techniques in data management system. Also state the advantages and limitations of each technique
What is the importance of combining different data collection techniques?
The importance of combining different data collection techniques balances the strengths and weaknesses of each other. It helps reduce non-sampling error and ensures improvement in data evaluation.

What is a description of the data and the organization of data into tables in a relational database?
The process of working out what data should go into which tables and how the tables should be related to each other is known as Normalisation.
How are locking techniques used for concurrency control?
Concurrency means use of database by many users at the same time.Concurrency control techniques (Different techniques) are used control multiple transactions interfere each other to produce wrong results. therefore one of the main techniques used to control concurrent execution of transaction is based on the concept of locking of data item. A lock is a variable associated with a data item in the database and describes the status of that item with respect to possible operation that can be applied to that item. Generally there is a one lock for each data item in the database.
Briefly explain the legal regulations in relation to data protection?

What are the types of sales organizations?
The sales organization represents the selling unit in the legal sense. It is responsible for example for product liability and other rights of recourse; customer deliveries; business partner contacts; and direct mailing campaigns. It also helps you to offset business operations internally.Different components use the sales organizationobject:G/L accounting (for account determination)Controlling (where the sales organization is used as a characteristic in profitability and market segment analysis)Quality management in shipping.Each sales organization is assigned to exactly one company code to which sales must be posted.You can structure a sales organization into several distribution chains. This determines the channel through which the sales organization can distribute materials and services. You can assign several divisions to a sales organization. The sales organization is then responsible for distributing materials or services for that division.Each sales area determines the distribution channel through which the products of a division are sold. Each distribution channel can be used by several plants, which in turn can be assigned to several different company codes. If a sales organization and a plant are assigned to different company codes, the system carries out an internal billing between the two company codes for each business transaction entry.You can define your own master data within a sales organization. Each sales organization has its own customer and materials master data, its own conditions and its own pricing policy.Since a sales organization cannot share master data with other sales organizations, you must create master data separately for each sales organization. However, you can create data for one distribution channel or division and then use it in others.If there is one sales organization for the company codeThe sales organization represents the company code Sales areas defined in the R/3 System are used to refine the structure of the external organizationEach sales area consists of the following R/3 organizational units (in any combination):Sales OrganizationsDivisionDistribution channelIf there is more than one sales organization for the company codePossible reasons for having more than one sales organization for each company code:· Different legal responsibilities, for example product liability· Unusual stipulations (for example legal), which make it necessary to distribute different product lines separately - for example, products for medicine and veterinary medicine· The desire to separate completely the sales activities of different enterprise areasSeparate distribution responsibilities, each with their own Marketing and Pricing policy - for example, one for the domestic market and one for exportOverlapping customer and product master records or the desire to maintain customer and product master data in a specific, unusual way· Overlapping responsibilities for order entry, or for sales and distribution processing (sales authorizations)If you set up several sales organizations for each company code, you must ensure that the system distinguishes between the different sales organizations when it deals with certain data, for example:· Customizing settings· Master Data· Transaction data.You do not need to set up several sales organizations for the following:· Different conditions· Fulfilling reporting requirementsYou can often use other groupings in such cases, for example, product hierarchy, customer group, distribution channel, division
Differentiate data and information and examples of each?
Well information is processed data. Information has more meaning than data. For example 0945 is data. In this state it doesn't mean much. But if you process it this data can mean for example a date: the ninth month of 1945 or it can mean 15 to 10.

Explain the difference between primary data and secondary data give an example of each?
Primary data is data collected firsthand, through surveys, interviews, experiments, etc. by the researcher, while secondary data is existing data that has already been collected by someone else. An example of primary data would be survey responses collected by a marketing team for a new product. An example of secondary data would be industry reports or census data obtained from a government website.
