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.
simple random sampling method
characteristics of sample
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
Pour plate method
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.
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.
we can get clear water from a given sample of a muddy water by the method of decantation.
