D) Weak negative correlation. A7. What is meant by time-series data? (A) A set of values which occurs sequentially in time. (B) A set of qualitative data. (C) A set of values which occurs randomly. (D) A set of marks obtained by a group of students. A8. The classical approach to time series analysis identifies four influences or components on the time series. Which of the following is NOT a time-series component?

scientific method has changed over time and if it is more less effective at achieving its goals? I will discuss this question in both sides during this essay. I preferred this question than the other questions because it is a strong question and I would like to discover more and research deeply in this investigation. The scientific method has been existing over a thousand years ago to be specific the science method started in the 17th century and methods of scientists has changed many times during

Making an Activity Series of Metals using different Solutions Purpose/ Hypothesis: The purpose of this lab was to clearly identify the reactivity of magnesium‚ zinc and copper. The metals reactivity will be exemplified as it will be tested with different solutions such as zinc sulfate (ZnSO4)‚ copper sulfate (CuSO4)‚ hydrochloric acid (HCL)‚ magnesium sulfate (Mg2SO4)‚ iron (II) sulfate (FeSO4) and tin (II) chloride (SnCl2). This will allow us in creating an activity series to visually see the reactivity

conducted in series and parallel to identify the pressure different in both pumps. Centrifugal pump is known as one of the most widely used pumps for transferring liquids. It’s also known as a device to transfer mechanical energy from a prime mover into fluid energy to produce the flow of liquids. The pump is connected in 2 ways; in series and another as parallel pump. Centrifugal pump are connected in parallel because to provide enough flow rates compare to centrifugal pump that connected in series‚ the

Chemistry Practical: Activity Series of Metals Introduction: The chemical activity of a metal is directly related to its practical use. In this investigation you will investigate the chemical activity of metals with oxygen‚ water‚ acid and alkali‚ to rank metals in order of their activity. Aim: To observe the reactivity of metals in order to determine the activity series of metals. Risk Assessment: In this investigation‚ hydrochloric acid solution is used which is toxic by all routes of

Title: Resistors in Series and Parallel Date: 17/7/05 Aim: The aim of this experiment is to compare the predicted and actual resistance in a circuit of resistor combinations in series and in parallel. Background: A resistor is an electrical component/device that has electrical resistance. Resistors can be used in electric circuits for protection of components‚ voltage division or current control. In an ideal resistor the resistance remains constant regardless of the applied voltage or current
