Data gathered in two different samples in such a way that there is a matching of the first sample data drawn and a corresponding data value in the second sample data. For example, compare two sample means, one for the first exam of the semester and the second for the second exam of the semester, match via the student taking each test.

Graphical method sample problem: Find the solution to the system of equations: 2x + 3y = 12 x - y = 3 Analytical method sample problem: Solve the system of equations using substitution method: 3x + 2y = 11 4x - 5y = -7
Use a graduated cylinder and the water displacement method. Pour the sample of water in the graduated cylinder and find its meniscus. That is its volume.
A scale can accurately measure protein content in a sample by using a method called the Kjeldahl method. This method involves weighing the sample, digesting it with acid to release nitrogen from proteins, and then measuring the nitrogen content to calculate the protein content. The scale ensures precise measurement of the sample weight, which is crucial for accurate protein content determination.
Pour plate method
No, Lowry's protein estimation method is not invasive. It is a biochemical method used to quantify the total protein concentration in a sample based on the reaction of proteins with specific reagents. It does not involve physical penetration or manipulation of the sample.
We define the access specifier of a function at the place of its method signature(The place we write the method's name).for example,public void sample(){}here "public" is the access specifier of function name-sample.
To calculate the mass in grams of each sample, you can use a balance or scale to measure the weight of the sample. The weight measured in grams is equivalent to the mass of the sample.
The convenience sample
A simple random sample is a method of selecting a sample where the probability of any particular member of the population being part of the sample is the same for all members of the population.
In external standard method we run a standard for the substance we are looking for in our sample and than run our sample in the same conditions. we will obtain peaks for the sample and standards and can correlate the sample with the standards and can determine the concentration of the same in our sample. for more details contact vani2007
