I have two apples, one banana, one cherry. Does it make sense to calculate the "average" of these things? Would you code that as a factor or a numeric value in R?
I don’t think that calculating average, in this case, is all that common? I cannot find average types of fruit. I cannot apply numerical techniques to the qualitative data. We say that it is a factor because the values of variables have qualitative values. Factors are describing the type of fruits and are represented by words and letters (Yakir, 2011). Therefore, the colors would be coded as factors. I have four quiz scores: 94, 93, 85, and 0. what is the mean (average) of my quiz scores? Would you code this as a factor or a numeric value in R?
In this scenario, I have to calculate the quiz scores by adding 94 + 93 + 85 + 0 = 272, and then divide by 4. The average of my quiz score is 68. This is a numeric data. Numerical data are numbers; we can count or measure it (Yakir, 2011).

What is the mean (average) of my grades? Would you code that as a factor or a numeric value in R? As what was articulated in question #1, factors are describing words and letters. There is no possibility of average in this scenario because the grades are not in numbers. So it is a factor and cannot be calculated as we do to
Raw scores are converted into percentiles since they have little clinical value. They are the original numerical values associated with the subject’s test performance which are converted into standard scores (Jarosewich, Pfeiffer, & Morris, 2002). The percentile rankings are normally used in scholastic and psychosomatic evaluation. Percentages illustrate ranking of those assessed performance as compared to the current student. Standard scores are the most useful of the test scores. These scores are normalized against the predetermined mean and standard deviation to detail the score’s distance from the average student. The greater one’s standard scores the better. Standard scores also enable better tailored-skill’s education for the individual’s continued growth. Standard scores are also defined against the standard error of measurement for each scale, which about three points. This produces a range within the student’s true score will fall.
Average AC value is calculated just by adding the median values of peak and valley median amplitudes.
7) Then collect the mean average using the results you received from repeating each of the tests.
Intelligence has begun to define individuals globally, but the goal of the minimum grading system is fairness and equality. Fair share grading is when all students in the class take an intended exam, but the class average score of the test is given to every student. Each student will receive the same grade even if one did better or worse than the average score. That being said it could reduce dropout rates, test anxiety, and competition between students. On the other hand, students could be affected negatively because it could lead to false self-value and unfairness to those students who study harder in order to earn higher grades. The debate continues about whether students should be separated by intelligence or be given equal grades in order
During my time producing lemonade at Colt’s Lemonade Stand I sold a lot of cups at my lemonade stand. My mean for cups sold at 27.48, the median was 22, the mode was 20, 28 and the range was 52. On day 4 I sold 52 cups because it was 94 degrees during that time we sold a lot because it was really hot.
The weighted scores for each area are added. The sum will fall in a range from one to nine. The total score will be carried out to the third decimal place.
This process is done by administering the test to a representative sample and using these scores to establish standards, usually referred to as norms, by which all individual scores can be compared. Since the average score is 100, experts can quickly evaluate individual test scores against the average of others to determine where these scores fall on the normal distribution.
mean for each question. Keep a record of the responses for each person who participates.
Students will not be given a numerical grade but rather, they have a scale which ranges from very good to needs practice. During the lower secondary years, students are aware that they are being tested. The next form of assessment is summative which is important since failure can prevent students from receiving their certificate of completion. Thus, this is more of an end of the year exam in lower secondary and upper secondary which will have verbal and numerical grading from four to 10, with five being a passing grade. However, teachers do not solely use the grades from the final exams. They will have a portfolio with the yearly assessments of students and the work students have done in grades eight and nine. The formal term for the exam given for upper secondary students is as I previously mentioned, the matriculation exam before the can attend university, polytechnic (university for applied sciences) or vocational schools (Tuovein,
First of all GPA stands for Grade Point Average. Your GPA is a reflection on your academics standing and are put on a scale that ranges from 0.0 to 4.0. Your GPA is so important because college/scholarship programs will need a certain GPA to offer admission and give financial aid. There’s 2 type of GPA: Un-weighted GPA and Weighted GPA. Un-weighted GPA uses the 4.0 scale to see how many points are earned per SEMESTER. Weighted
The mean summarizes the properties of the group. It’s important to understand that the mean does not represent an individual – there may be no individual whose value matches the mean; but the mean is a summary of the entire population. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. The sum divided by the count.
It changes from blue to red with acids but loses its colour in the presence of certain chemicals, one of which is vitamin C. DCPIP solution can be used to test for the presence of vitamin C in foods. Hypothesis Orange juice has the highest content of vitamin C. Citrus fruits have a higher content of vitamin C. The orange and lemon juice contain more vitamin C than the pineapple juice. Furthermore, as lemons are more acidic than oranges, I predict that the orange juice will contain more vitamin C than the lemon juice. Vitamin C affects, the ph the more vitamin C the higher the ph. Variables Independent Variables Different fruit juices (Pineapple, orange and lemon).
Teachers have always used grades to measure the amount a student has learned. This practice is becoming ineffective. Many students have a wide range of grades, which show that grades may not show what a student really knows. Therefore, the standard grading system should be replaced. Some reasons why grades should be replaced are bad grades can hinder a child’s performance, grades define who a student is in the classroom, and grades are not an effective way to see if students have learned the material. The current grading system should be upgraded and every school should incorporate the plus/minus system in their method of grading.
