Princess Faye N. Balatero Grade 8-Br. Edmund Hubert FSC Introduction: Statistics are used everywhere; we see statistics in use every day; statistics is used to answer important and practical questions. Statistics are useful in almost all disciplines. They are used in statistical analysis of results of an experiment‚ prediction of future values‚ growth and trend analysis‚ systematic presentation of data in the form of tables‚ diagrams and

MB0040 – Statistics for Management - 4 Credits (Book ID: B1129) Assignment Set - 1 (60 Marks) Q1. Define “Statistics”. What are the functions of Statistics? Distinguish between Primary data and Secondary data. Answer: Statistics is usually and loosely defined as: 1. A collection of numerical data that measure something. 2. The science of recording‚ organizing‚ analyzing and reporting quantitative information. Professor A.L. Bowley gave several definitions of Statistics. He defined

9.18 a) Using forward stepwise regression to find the best subset of predictor variables to predict job proficiency. The Alpha-to-Enter significance level was set at 0.05 and the Alpha-to-Leave significance level was set at 0.10. The first predictor entered into the stepwise model is X3. SAS tells us that the estimated intercept is -106.13 and the estimated slope for X3 is 1.968. The R2-value is 0.8047‚ mean square error is 76.87. The second predictor entered into the stepwise model is X1.

Mental Mathematics is the ability to utilise mathematical skills to solve problems mentally. The marks scored by pupils generate statistics which are used by teachers to analyse a student’s performance and development of theories to explain the differences in performance. The Standard 3 class is where the transition from junior to senior level occurs where teachers expect the transference

Chapter 2 Charts and Graphs Statistics is the science of data. A first step in the study of statistics is the examination of data. Chapters 2 and 3 present several techniques for reducing data so that it is more manageable. In addition‚ graphic displays are essential to understand and interpret complex sets of data in order to be able to make business decisions easier. Chapter 2 discusses and displays several graphical tools including the histogram‚ frequency polygon‚ ogive‚ dot plot‚ bar

follows a path determined by the effects of gravitational acceleration and air resistance. Projectile motion is the act of projecting an object into the air at an angle when a curved path is an object follows when thrown or propelled near the surface of the earth.For example: a thrown football‚ an object dropped from an airplane‚ or a bullet shot from a gun.Projectile motion may only be used to solve mechanics problems if the acceleration is constant.The path followed by a projectile is

Investigating Projectile Motion Introduction Projectile motion is a type of motion that consists of horizontal and vertical motions which are independent from each other‚ known as vector components. For an object to be considered a projectile‚ it must not be self-propelled. Projectiles move horizontally at a constant velocity. However‚ they undergo uniform acceleration in the vertical direction‚ which is caused by gravity. An important aspect of projectile motion is that the time it takes
