I. Methods of research to be used Descriptive research can involve collecting quantitative information‚ or it can describe categories of information such as patterns of interaction when using technology in the classroom. Although it may employ fundamentals of both quantitative and qualitative research‚ descriptive research does not fit neatly into the definition of either quantitative or qualitative research methodology. Descriptive research may be used most effectively within the educational

regulate or research the effects of chemicals on living organisms can cause many health risks to their citizens and the environment. One such instance in history is in the United States of America after World War II‚ where synthetic chemical pesticides used by the government and farmers grow crops. Rachel Carson researched on why these pesticides were unsafe for humans‚ animals and especially nature. Rachel Carson fought to bring global attention to the use of chemicals. As well as launching the awareness

Plan a procedure that will allow you to compare quantitavely the glucose concentration in fresh samples of orange‚ lemon and grapefruit juice. Aim: The aim of this investigation is to produce a set of data which will enable comparison of the glucose concentrations of orange‚ lemon and grapefruit juice. Research: Benedict’s Reagent is a mixture of sodium compounds and copper sulphate. The copper ions are reduced by fructose (a reducing sugar) to form copper oxide‚ thus turning it from blue

Chapter 9 Recommended Methods for Determining Soil Cation Exchange Capacity Donald S. Ross and Quirine Ketterings The cation exchange capacity (CEC) of a soil is a measure of the quantity of negatively charged sites on soil surfaces that can retain positively charged ions (cations) such as calcium (Ca2+)‚ magnesium (Mg2+)‚ and potassium (K+)‚ by electrostatic forces. Cations retained electrostatically are easily exchangeable with cations in the soil solution so a soil with a higher CEC

Statistical Analysis of Colored Stones by using Random Sampling Naomi Malary Lab Report 1 Ecology Lab 312 L-1 October 12‚ 2009 Introduction Random Sampling‚ a method often used by ecologist involves an unpredictable component. In this method‚ all members of the population have an equal chance of being selected as part of the sample. The results involving random sampling can be categorized as descriptive statistics and inferential statistics (Montague 2009).Descriptive statistics

In recent years‚ many banks are experiencing a decrease in the traditional deposit funding sources and thus failed to keep up with the growth in bank assets. To make up for this decrease‚ banks supplemented their funding with less stable and more expensive funding instruments‚ together with cutting back on their holdings of cash and securities and selling or securitizing parts of their loan portfolio. These have increased the challenges that banks face in maintaining stability and profitable operations
