    @zareen said in STA630 Assignment 1 Solution and Discussion: sampling and sampling technique Sampling is the process whereby some elements (individuals) in the population are selected for a research study. The population consists of all individuals with a particular characteristic that is of interest to the researchers. If data are obtained from all members of the population, then we have a census; if data are obtained from some members of the population, then we have a sample. With probability sampling, a researcher can specify the probability of an element’s (participant’s) being included in the sample. With non probability sampling, there is no way of estimating the probability of an element’s being included in a sample. Although often more difficult and expensive, probability sampling is a methodologically more precise method to obtain a sample that is representative of the population. With simple random sampling, each individual in the population has an equal chance of being selected for the sample. The four steps of simple random sampling are (1) defining the population, (2) constructing a list of all members, (3) drawing the sample, and (4) contacting the members of the sample. Stratified random sampling is a form of probability sampling in which individuals are randomly selected from specified subgroups (strata) of the population. This method can be used to increase the representativeness of the sample and/or to allow comparisons to be made among individuals in the different strata. Convenience sampling is quick and inexpensive because it involves selecting individuals who are readily available at the time of the study (such as introductory psychology students). The disadvantage is that convenience samples are generally less representative than random samples; therefore, results should be interpreted with caution. Quota sampling involves the selection of a certain percentage of individuals from specified subgroups of the population when the population is large and lists of members are not available. Many polling organizations use this technique. Appropriate sample size depends on various considerations, including population variability, statistical issues, economic factors, and availability of participants. In general, with larger samples you will have a smaller margin of error and you can detect smaller differences. The larger the variability of scores in the population, the larger the sample must be in order to be representative. Sampling error includes systematic error and random error.Systematic error occurs when the sample is not properly drawn (an error of the researcher). Random error is the degree to which the sample is not perfectly representative of the population. Even with the best sampling techniques, some degree of random error is expected. Increasingly, we are exposed to information based on sample data. Understanding the principles of sampling, particularly the limitations of various methods, should make us more critical consumers of such information.

    Solution Idea: Answer No.1: How decision support system helps to organization: Helps in Decision Making. Decision support systems (DSS) are interactive software-based systems intended to help managers in decision-making by accessing large volumes of information generated from various related information systems involved in organizational business processes, such as office automation system, transaction processing system, Enhance effectiveness. A second category of advantage that has been widely discussed and examined is improved decision making effectiveness and better decisions. Decision quality and decision making effectiveness are however hard to document and measure. Most researches have examined soft measures like perceived decision quality rather than objective measures. Advocates of building data warehouses identify the possibility of more and better analysis that can improve decision making. Improve interpersonal communication. DSS can improve communication and collaboration among decision makers. In appropriate circumstances, communications- driven and group DSS have had this impact. Model-driven DSS provides a means for sharing facts and assumptions. Data-driven DSS make “one version of the truth” about company operations available to managers and hence can encourage fact-based decision making. Improved data accessibility is often a major motivation for building a data-driven DSS. This advantage has not been adequately demonstrated for most types of DSS. Competitive advantage. Vendors frequently cite this advantage for business intelligence systems, performance management systems, and web-based DSS. Although it is possible to gain a competitive advantage from computerized decision support, this is not a likely outcome. Vendors routinely sell the same product to competitors and even help with the installation. Organizations are most likely to gain this advantage from novel, high risk, enterprise-wide, inward facing decision support systems. Measuring this is and will continue to be difficult. Part-(b) Identify the techniques & DSS model in each of the following example scenario S.NO Scenario Technique DSS MODEL 01 What would happen to sale when you cut down advertising cost 20 % What if analysis Model Driven Model 02 Increase the cost of advertisement until sale reach to $ 2 million Goal Analysis Model Driven Model 03 Find out about this year revenue in compare to previous year Data Mining Data Driven Model 04 Past admission analysis using exploration of data and discovering features and pattern Data Mining Data Driven Model 05 To receive 950 dollars what number of item must be solved at the cost of 10$ Data Mining Model Driven Model 06 What is the prediction on sale of next year Data Mining Data Driven Model Question no 2: Identify the type of information system or related sub system that describe the following scenario 01 Management information system to measure the success of your client with your product service 02 Content Management System used to manage contacts, forecast and generate reports for sale 03 Management information system that maintain the correct amount of inventory and notify when under stockage occur. 04 Management information system that guaranteed that produced or completed material shipped to the consumer complies with the company’s quality standards 05 CUSTOMER RELATIONSHIP MANAGEMENT SYSTEM used to notify the customers about product recommendation based on the previous order 06 Material requirement planning system Tracks the whole conversion process of raw material into the finished goods Part-(b) Three point between project life cycle and software development life cycle (SDLC) PDLC SDLC PDLC is defined as a process that is responsible for bringing to market a new product and generally includes the business units. SDLC on the other hand, is used for developing particular software products. SDLC is primarily aimed at solving a specific software problem that may arise. PDLC Phases Are As Follows Idea generation and screening Research Development Testing Analysis Introduction SDLC Phases Are As Follows Requirements gathering or analyzing user requirements Designing the program Coding the program Documentation and testing of the system The project lifecycle concerns itself more with the planning and user facing aspects such as Plan, Execute, QA, UAT, Go Live! The SDLC involves steps such as develop, build, test, and promote, debugging/fix.

    Q.1 Solution: Camera Jib: Device that’s come into wide use in the last decade is the camera jib, essentially a long, highly maneuverable boom or crane-like device with a mounted camera at the end. You frequently see them in action swinging overhead at concerts and major events. A jib allows sweeping camera movements from ground level to nine meters (thirty feet) or more in the air. Camera Copters/ Drone Cameras Since remotely-controlled, helicopter-type drones can move into places inaccessible by individuals or fixed-wing aircraft, they can provide coverage of events otherwise unattainable. Plus, helicopter type drones can hover above news scenes for extended periods of time. The video signal is relayed (live) to a receiver on the ground. Q.2 Differentiate the below given camera movements while giving an example of each. ・ Dolly ・ Trucking Answer: We refer to moving (rolling) the entire camera toward or away from the subject as a dolly (“dolly in” for a close shot or “dolly back” for a wide-shot). A lateral move (rolling the camera to the left or right on the pedestal) is trucking, as in “truck left” or “truck right.” [image: AMUs1yx.png]

    Solution: Many directors believe that “cast right and half of your job as a director is accomplished.” The statement at best is a half-truth. In this era of star-making projects, the politics of finance as often as a director’s vision dictate casting. The rise of powerful agents and casting directors have moved the pendulum in the direction of political rather than creative casting. My comments that follow are only relevant to creative casting (let me just say that directors must continue to fight to maintain their vision of the characters in their films). Casting is the first expression of the director’s idea before production begins—all the more reason why the director at this preproduction stage must have a clear director’s idea, which, at this stage, is based on an interpretation of the script. The casting process is first and foremost about the look of an actor. Whether or not the actor physically conforms to the director’s vision of the character is less important than a checklist about the qualities, both physical and behavioral, the actor projects. I would suggest that at this first meeting between the director and an actor and the reading that will follow that the director keep a list of criteria by which to assess the actor, such as: Professionalism Level of tension the actor brings to the situation 3. Energy Charisma All-time hit PTV classic Drama Waris had a character of Choudhary Hashmat played by veteran acot Mehboob Alam. Chaudhry Hashmat’, the protagonist of his famous play, Waris, who thought the common people were like trees who needed pruning to check them from rising above their apportioned height and growing to their natural stature, years before Karl Marx had stated that the source of people’s poverty was the rich man’s wealth.
