Introduction Wrong or inaccurate measurements can lead to wrong decisions‚ which can have serious consequences‚ costing money and even lives. The human and financial consequences of wrong decisions based on poor measurement being taken in matters as important as environmental change and pollution are almost incalculable. It is important therefore to have reliable and accurate measurements which are agreed and accepted by the relevant authorities worldwide. Metrologists are therefore continuously

In The Laboratory‚ the courtesan chooses poison as her murder weapon. Poison is often the weapon of choice for female killers. It requires little or no physical strength to administer‚ and can be done secretly. It also leaves little evidence thus making it difficult to detect the culprit. We believe the act of murder is because of another woman that her lover is with and she feels physically inferior to her rival. We know this because she starts saying ‘What a drop! She’s not little‚ no minion like

3. DATA MINING TECHNIQUES 3.1 NECESSITY OF DATA MINIING DATA Data is numbers or text which is a statement of a fact. It is unprocessed and stored in database for further analysis. Operational and transaction data such as cost and sales‚ is essential to modern enterprise’s internal environment. Non-operational data such as competitors’ sales and forecasting data‚ is responsible for analysis of external environment. INFORMATION Information is generated through data mining so that it becomes

prepare and standardize HCl solution. INTRODUCTION Standardization is a process of determining the relationship between the measured signal and the amount of analyte. Standardization can be defined also as a titration experiment in which the concentration of a solution becomes known to a high degree of precision and accuracy. In a standardization experiment‚ the solution being standardized is compared to a known standard. This known standard can be either a solution that is already a standard solution

Theory The first experiment focused on the concept of errors and uncertainties that are obtained during measurements. For an experiment to be successful‚ especially those that involve measurements‚ the number of significant figures must be known. Significant figures are the digits required to express a measured quantity and thus reflect the accuracy of the measurement. Uncertainty is defined as the smallest increment that can be measured and is defined by the instrument used. An error is defined
