Graphical Techniques to describe a set of Interval data ( cross-sectional data ) A. Histogram ~ A histogram is created by drawing rectangles whose bases are the class intervals (classes) and and whose heights are the frequencies. Determining number of class intervals No. of Observations No. of Classes 50‚000 17 - 20 ~ Alternatively using Sturges’s formula No. of class intervals = 1 + 3.3 log(n) where n = No. of observations ~ Determining class interval widths Class width = (Largest Observation

Collinear is passing through or lying on the same staright line. Coplanar is lying on or occurring in the same plane. Define Non-Collinear Points The points which do not lie on the same line are known as Non-Collinear Points Below diagram represent‚ Non-Collinear Points P‚ Q‚ R & S. In the above Diagram‚ Points P‚ Q‚ R & S doesn not falls on the same line and Hence they are called Non-Collinear Points. | Coplanar Definition of Coplanar * A set of points‚ lines‚ line

Which type of surface will produce the fastest race time? Concrete‚ sandpaper‚ or gravel? If I race a remote control truck on a concrete‚ sandpaper‚ and gravel surface‚ I think the truck will go faster on the concrete surface. 1. Gather all of your materials. 2. Using your measuring tape‚ measure 12 ft in distance from the starting point to the finish line. Make sure your area is flat and dry. 3. Stick pieces of tape at the beginning and end of your track to form a clear

Activity 1.1.2: Crime Scene Search Methods Link Method Method is not a geometric pattern or easily definable. There is no set pattern. The method requires the investigator to be able to form logical links between crime scene activity and the likely places additional evidence could be found at the scene as a result. Method seeking to find associations between evidence. Investigators evaluate the scene and then proceed through the area in a systematic and logical fashion. Based on the

Two Variable Inequality MAT 221 11 May 2012 The purpose of this week’s assignment is to determine how many maple rocking chairs the Ozark Furniture Company can make. We will also plot the inequalities of this on a graph. Here is the information and first set of problems for the text: Maple rockers. Ozark Furniture Company can obtain at most 3000 board feet of maple lumber for making its classic and modern maple rocking chairs. A classic maple rocker requires 15 board

The Domino Effect 9-26-01 Abstract: In this experiment dominos were used to investigate how distance‚ time‚ and average speed is interrelated by maximizing the speed of falling dominoes. This was done by lining up 28 dominos up against a meter stick 0.5 cm‚ 1.0 cm‚ 1.5 cm‚ 2.0 cm‚ and 2.5 cm away from each other. Before the experiment the average width of a domino was taken. At the beginning of each of these 5 trials the dominos were lined up against the meter stick. The lengths of all the dominoes

Introduction The basic premise behind the learning curve concept is the improvement in performance of process due to repetitive nature of tasks operated by individual or organization again and again. This theory is based on three fundamental assumptions which is as follows: 1. The time required for completion of task decreases as it is repeated number of times 2. The percentage of improvement decreases with corresponding increase in volume of units‚ 3. The rate of improvement is predictable over

Rudolf Laban (1879-1953) was born in Austro-Hungary. Laban became interested in the relationship between the moving human form and the space which surrounds it. He was a dancer‚ a choreographer and a dance / movement scholar. Laban was the first person to develop community dance and he set out to reform the role of dance education‚ emphasizing his belief that dance should be made available to everyone. Laban believed that movement enables a man to recognize his physical potential and that movement

Chapter 2 1. A consumer prefers more to less of every good. Her income rises‚ and the price of one of the goods falls while other prices stay constant. These changes must have made her better of. TRUE 2. A decrease in income pivots the budget line around the bundle initially consumed. FALSE 3. If all prices are doubled and money income is left the same‚ the budget set does not change because relative prices don ’t change. FALSE 4. If all prices double and income triples‚ then the
