What is the textual form of presenting data?

In order to publish an article, scientific journals require the writer to have findings, ideas or other information worth reporting to the field in which the publication specializes. In addition, the journals require the scientist to present his ideas in a manner consistent with the publication's expectations. Publishers look for material that is of interest to the readers of the journal.\nScientific journals look for information that is timely and up to date. The scientist reviews other published articles in the area of his study and credits the research of others upon which he bases his..

What is 66 and two-thirds as a fraction?

All numbers can be written as a numerator over denominator. A whole number of 66 is simply a fraction with 66 as the numerator and one as the denominator. Multiply the top and bottom by 3 in order to obtain a common denominator with 2/3. Adding 198 over 3 and 2 over 3 yields a final fraction of 200 over 3.

What is the difference between qualitative and quantitative analysis?

A scientific study usually employs both methods of observation, but will tend to rely more heavily on one or the other dependent upon the subject of the study. In the field of psychology, there are many quantities that can be measured. However, there are many nuances that would be missed if the researcher were to rely too heavily on quantitative data alone.\nThe quantitative data provides the framework of the study. Many times a study is only concerned with a particular gender and age group, such as males from 18-35 years old. A certain condition or its absence might be another determining fac..

What is the standard deviation of a binomial distribution?

\nAs an example, imagine a coin that is flipped 100 times, with a binomial distribution defined by the number of heads. In this case:\nn = 100\np = 0.5\nμ = np = 100 x 0.5 = 50\nσ = √100 x 0.5(1 - 0.5) = √25 = 5\nIn other words, out of 100 coin flips, one can expect the number of heads on average to fall between 50 +/- 5, or between 45 and 55.

What is inter-rater reliability?

Reliability tests assess whether results of any assessment are both stable and consistent. Inter-rater reliability is only useful when something or someone is assessed by two or more people.\nInter-rater reliability is often used when artifacts, portfolios or other subjective items are being judged, as it compares the opinions of the raters. For strictly objective measurements, retests and alternative forms of the measurement are used.

How do you graph quadratic functions?

Plot a minimum of seven points from the quadratic equationEnter the integers -3 through 3 as the x-values in the equation. Calculate the corresponding y-values, and place both x-values and y-values in a T chart. Draw an x-axis and y-axis on graph paper, and graph the points.Draw a provisional curve through the pointsLook at the points to see if connecting them forms a "U" shape that faces upward, downward or to one side. If the points resemble a gradually flattening line, plot more points near the flatter part of the line. Once you have enough points, draw a curve through the points to create ..

How is cubic capacity figured?

For example, one engine has four cylinders each with a bore of 8.1 centimeters with a stroke of 7.76 centimeters. The formula is 0.7854 times 8.1 times 8.1 times 7.76 times 4. This produces a product of 1,599.5 cc. The volume of cylinders is measured with special burettes filled with paraffin.

What is meant by reasonableness in math?

In less complicated math problems, a rough and mentally-calculated estimate, sometimes referred to as a "ballpark estimate," can help to predict the numerical range the final answer should fall within. For example, if the given problem is to determine the sum of 23 plus 76, it can be estimated that the final and precise answer will be somewhere close to 100 because the known calculation 25 plus 75 equals 100 is close to the given problem 23 plus 76. Younger students are often taught to check the reasonableness of their final answers by comparing them to a ballpark estimate.Another method of es..
