Presentation, Analysis and Interpretation of Data Presented By: Lovely Ann F. Hezoli Objectives After studying this lesson you are expected to: 1.Be able to present the results of your collected data. The load and demand curves in transmission, and distribution systems can be analyzed with graphical analysis. The end result is a set of vertical lines of evenly-spaced dots. This tool enables to see all the values of a data set even if there are similar data points. A turning point for both lines. Graphical Representation Graphical Representation is a way of analysing numerical data. It comes in the form of a two-dimensional chart and has a radial axis and an angular axis. Compute the time to duplicate a file that happened... le 47 AT Load T. AT: Figure Q5(a) (b) A three phase half-wave uncontrolled rectifier is connected to inductive load. Time Series Analysis is the analysis of the plotted data in order to get meaningful information out of it. In our example… 1952: A peak of the mice line and a low of the kestrel’s line. In engineering there are many key concepts and terms that are crucial for students to know and understand. 100 V 0.01Â°F volt) Figure 1: Problems 1 and 2. Graphical methods are also a key component of exploratory data analysis (EDA). Problem 1 (10 points): Design an inverting amplifier with gain of A, = -20 using an ideal op-amp and resistors of any value. If the result of addition is < (0011), ac... Q3. The graphs help in making summaries of characteristics of data in effective and efficient manner. (2 marks) 10 Î© ÏÏ + HH 3 mF 5 Î© 4.5 nA 13 Î© ÎÎÎ 7Î© In EDA, various graphical techniques are used initially to display data for qualitative assessments prior to selecting appropriate statistical tests. They are often used for comparing distributions that have small number of data. R3 =4.7k and the voltage sources are: V1 =12v, V2=10v 1. A graphical analysis based on the impedance-matching technique and the measured interface shock velocities was used to determine a Hugoniot point for each lower layer sample relative to the molybdenum standard and for each upper layer sample relative to … After plotting the data, a point close to the center indicates a low value and a point near the edge indicates a high value. First, install the program or decide what you will use. It shows where the data are clustered, where the gaps are located and can help identify outliers. 1.2.1Univariate analysis If the analysis concerns one single variable, it is a so called univariate analysis. (2 marks) R w R C CL ell L Lj 2 V -C R R 2R. For example, questions about patterns in the data and whether one variable changes when another changes are often easier to see in a … Some of the various graphical methods in statistics. Brief descriptions of some useful statistical plots are presented in the subsections below. Often it can be hard to determine what the most important engineering concepts and terms are, and even once youâve identified them you still need to understand what they mean. We've got you covered with our online study tools, Experts answer in as little as 30 minutes. They focus on the absolute value of the data while a pie chart focuses on the relative value of the data.
