Measurements and Error Analysis‚ #1‚ Chris Baca Discussion of differences The purpose of this experiment is to understand why we have variances in measurements and how to reduce the variances. When taking a measurement there are multiple factors that affect its value. The more the measurement is taken the measurements average is closer to the actual value. Other factors include the instruments calibration‚ cleanliness of the inside of the measuring arms and human error in reading the measurements

The discovery of copper does not have an exact date. Copper is said to be a prehistoric element. This element was said to be first discovered around 8000BC. The ancient civilizations started to take the copper out of the ore they found around 4000BC. This is when copper started to be put to good use. Early civilizations discovered that copper is malleable and is sharp. They realized they could make copper into tools and weapons. This was easier than the stone that they were originally using. This

DATA NEEDED IN EDUCATIONAL PLANNING STATISTICS is the study of the collection‚ organization‚ analysis‚ and interpretation of data. It deals with all aspects of this‚ including planning of data collection in terms of the design of surveys and experiments. A Statistician is someone who is particularly well versed in the ways of thinking necessary for the successful application of statistical analysis. Such people have often gained the experience through working in any of a wide number of fields

Abstract In this experiment‚ the absorbance of KMnO4 was measured by spectrophotometric method to determine the molar concentration and the molar extinction coefficient of KMnO4. In part 1‚ in order to determine the maximum absorbance wavelength of KMnO4‚ we measured the absorbance of the sample solution which contains KMnO4 at the wavelengths between 330nm and 660nm‚ and plotted the λ and A points; the λmax was 530nm. In part 2‚ the effect of concentration on the absorbance was examined. We prepared

MAF202 Money and Capital Markets – Assignment Executive Summary Quantitative easing (QE) is a monetary policy that stimulates economic activeness. QE was first originated in Japan at 2001‚ afterward‚ the policy showed its power to influence the economic performance (Kamada &Takagawa‚ 2005). In 2008‚ most countries in the world were suffered by Financial Crisis which caused by subprime mortgage. Consequently‚ the United States and Euro Union implement the first round of QE‚ in order to recover

Central Bank (ECB)‚ among others‚ have embarked on monetary easing or quantitative easing. This is an unorthodox way of pumping money into the economy and aiming to lower the long-term interest rates in order to combat a recession. Since interest rates in industrial countries had declined to near zero in the aftermath of the global crisis‚ the scope for further monetary easing through lower policy rates became very limited. Quantitative easing (QE) and other asset purchase programs have therefore been
