how much dissolved oxygen is found in the water when no fish is present. Then‚ measure the water with fish in it‚ increasing by 2 every time. Record the amount of fish and dissolved oxygen in a chart. When about 20 fish is reached‚ stop recording and put all the data into a line graph. Using a line graph will help see any patterns between dissolved oxygen and number of fish. 4.

INTRODUCTION Gozinto Chart named after an Italian mathematician Professor Zepartzat Gozinto is from the word ‘goes into’ is used to provide overall microview of how materials and subassemblies are united to form finished products. It is often called Assembly chart (Shim and Siegel‚ 1999) In other words‚ it is a pictorial representation of a product that shows how the elements required to build a product fit together. Gozinto Chart is a schematic model that defines how parts go together‚ the order

Pie Charts An important part of decision making is having a clear understanding of the information used to base decisions from. Charts can be valuable when a need to represent numerical data would benefit communicating information visually. Some of the most important aspects of a good chart are to select the right type of chart (or graph) that can best characterize the data‚ also‚ to keep the design simple in order for an audience to easily understand the information. One of the most popular types
Premium Pie chart Chart Bar chart
Standard. Here it is a dimension such as the contents of a jar of fruit jam‚ the size of a pair of shoes etc. These are called X-bar and R charts. One calculates X-bar-bar and R-bar averages and these are the centre lines of the SPC run-charts that will be drawn. The charts MUST have these centre lines PLUS upper and lower control AND range limits. The points on these graphs MUST be joined so that a reader can follow the level of quality versus centre lines and control limits over time and look for trends

Control Charts Control charts‚ also known as Shewhart charts are tools used to determine if a manufacturing or business process is in a state of statistical control. The control chart was invented by Walter A. Shewhart‚ (also known as the father of statistical quality control) while working for Bell Labs in the 1920s. The company’s engineers were seeking to improve the reliability of their telephony transmission systems. The engineers had realized the importance of reducing variation in a manufacturing

We don’t say data structurehere and see the difference. Graphs mean to store and analyze metadata‚ the connections‚ which present in data. For instance‚ consider cities in your country. Road network‚ which connects them‚ can be represented as a graph and then analyzed

Introduction in Graph Theory (BASIC CONCEPTS) BASIC CONCEPTS We used decision trees in Unit DT and used them to study decision making. However‚ we did not look at their structure as trees. In fact‚ we didn’t even define a tree precisely. What is a tree? It is a particular type of graph‚ which brings us to the subject of this unit. What is a Graph? There are various types of graphs‚ each with its own definition. Unfortunately‚ some people apply the term “graph” rather loosely‚ so

1.2 Basics of Functions and Their Graphs Introduction to Relations Domain and Range of a Relation Any set of ordered pairs (x‚y) is called a relation in x and y. Furthermore‚ The set of first components in the ordered pairs is called the domain of the relation. The set of second components in the ordered pairs is called the range of the relation. Definition of Function and Vertical Line Test Definition of a Function Given a relation in x and y‚ we say “y is a function of x” if for every

Graphs‚ Groups and Surfaces 1 Introduction In this paper‚ we will discuss the interactions among graphs‚ groups and surfaces. For any given graph‚ we know that there is an automorphism group associated with it. On the other hand‚ for any group‚ we could associate with it a graph representation‚ namely a Cayley graph of presentations of the group. We will first describe such a correspondence. Also‚ a graph is always embeddable in some surface. So we will then focus on properties of graphs
