possible to reduce uncertainties in the distance * Align the center of the lens with the wick of the candle. 2. Place the lens at 200mm from the candle 3. Move the paper along the ruler until a clear image is obtained 4. Record measurements 5. Repeat experiment at least 3 times every 20mm along the ruler. Data: Data showing the image and object distance (mm) from the lens ±30mm | Object distance (u) | Image distance (v) | | 1 | 2 | 3 | Average - 10% | 200 | 610

Analyse and evaluate information and interpret results a) Interpret results (2m) – give a possible biological explanation for results b) Evaluation of data comment on precision and reliability, accuracy of the data (state which set of measurement is more reliable, state which experiment is more accurate). Comment on the validity of the results. (if accuracy and reliability used wrongly, means A2 is D) c) A discussion of errors and their impact on the results * Sources of Random

How is Lab Glassware Used? Luis Cervantes, Ruby Morales, Justin Oursler, Cole Von Roeder Friday September 4, 2015 10:30 am Kaitlyn Mandigo Section L52 Introduction: The intention of this investigation was to find the most precise and/or accurate glassware. Precision is how close the measured values are to each other, and accuracy is how close the measured value is true to the value. To do this different laboratory glassware was

P3, M2 1. Pulse Rate It’s the rate per minutes at which your heart beat. It can be felt wherever an artery crosses a bone such as the wrist, the neck or either side of the windpipe, temple and the upper surface of the foot. It can be measured by pressing lightly against the artery wall with 2 or 3 fingers, apart from the thumb as this has a pulse of its own. Count the number of beats in a set of period and multiply the correct multiple to make up 60s or count for 30s and multiply by 2. In order

three-step process of measuring actual performance, comparing actual performance against a standard, and taking managerial action to correct deviations or to address inadequate standards. (See Exhibit 18-2.) The control process assumes that performance standards already exist, and they do. They’re the specific goals created during the planning process. Exhibit 18-2 The Control Process Step 1. Measuring Actual Performance To determine what actual performance is, a manager must first get information

Raj Nathwani Chemistry 201 Laboratory 2: Density Measurement Introduction: The purpose of this laboratory exercise is to introduce basic laboratory measurements, with a specific emphasis on the units of mass and volume. Familiarization with measuring mass and volume, and calculating density from the results will also be executed. The overall goal of the laboratory is for the student to be able to draw conclusions on the relation between the position of metals on the periodic table

EXPERIMENT 1 UNCERTAINTY AND ERROR ANALYSIS INTRODUCTION Physics is a field of Science, which is quantitative in nature. The purpose of doing experiments in Physics is mainly to collect and analyze the data. In all measurements, there is always some uncertainty associated with the values. The uncertainty may be because of systematic errors or random errors or both. The errors in a particular experiment may be due to the observer, or to the instrument used, or to a combination

Example of qualitative is a type of car and for the quantitative variables is the number of runner in the marathon. 6. Explain the difference between a sample and a population Population is the entire of individuals or objects of interest or the measurements obtained from all individuals or objects of interest. A sample taken from population, so that’s mean the sample is a proportion. 7. Explain the difference between a discrete and a continuous. Give an example of each not included in the text
