the tip . When the operating button is pressed again ‚ the piston descends ‚ expelling the liquid from the tip. We need to optimize volume range by selecting the correct volume pipette . We must work in the 35% to 100% volume range for best accuracy and precision . Besides that ‚ the tip immersion angle also plays an important role . Nextly‚ the micrometer setting must be done using the correct technique . If filled ‚ we should not lay the pipette down or hold more than 20º from vertical . Lastly

(Actual value – estimated value/actual value) x 100: Subtract estimated value from actual value. Then divide by the actual value and multiply the answer by 100 7. Repeat the previous 1-6 steps while performing an additional two trials to ensure accuracy. Record results 8. Determine the averages for the three previous trials 9.

‘Formality’ is very important‚ as academic writing is to inform the reader on a subject‚ it is not to be entertaining. Writing should be up to a formal standard‚ like broadsheet papers‚ textbooks and journals. As writing has to be a high standard‚ ‘Precision’ should also be considered. However this type of writing might be more relevant to scientific writing‚ giving facts and figures precisely. There is however a general rule that applies to all types of academic writing‚ which is objectivity. All academic

Sample test: Quantitative Method for Business Research Note: This sample test is just a sample for you to see what a real exam looks like. That means that it is not necessarily same as a real exam. 1. Any measure to characterize a variable of a sample is called a) a sample b) a census c) a statistics d) a parameter 2. The score of student’s aptitude test is an example of a) a categorical nominal data b) a categorical ordinal data c) a continuous interval numerical data

were found to be 100 and 1250 ng/ml respectively. Tamulosin Hydrochloride and Finasteride were found to be linear in the range of 0.3 to 10 µg/ml and 3.75 to 125 µg/ml respectively. The developed method was validated in terms of linearity‚ accuracy‚ precision‚ specificity‚ limit of detection‚ and limit of quantification as per ICH guidelines. System suitability parameters like number of theoretical plates (N)‚ peak asymmetry factor (As)‚ and resolution (Rs)‚ etc. were studied and it was found that

What Do Mathematics and Being a Math Teacher Mean to Me? Mathematics‚ for me‚ is a science of systematic way of thinking. Symbols (e.g. numbers) are meant for representation‚ accuracy and precision. Mensuration‚ which is very useful both in practical purposes and other sciences‚ is a great example as proof. Manipulation of these symbols produces systematic representation and pattern. For an instance‚ an individual who is good in constructing‚ determining‚ and manipulating equations as well as inequalities
