1. For the following scores, find the mean, median, and the mode. Which would be the most appropriate measure for this data set?

Statistics provides us with very useful tools and techniques that aide us in dealing with real world scenarios. I have been able to learn several useful concepts by studying statistics that can aide me in making rational and informed decisions that are supported by the analysis results. Statistics as a discipline is the application and development of various processes put in place to gather, interpret, and analyse the information. The quantification of biological, social, and scientific phenomenons, design and analysis of experiments and surveys, and application of

(2) Give that a sample of 25 had x = 75, and (x-x)² = 48 the mean and standard

4. Calculate the following measures of central tendency for the set of cube measurement data. Show your work or explain your procedure for each.

5. Give the standard deviation for the mean and median column. Compare these and be sure to identify which has the least variability?

1. By hand, compute the mean, median, and mode for the following set of 40 reading scores:

• Provide at least two examples or problem situations in which statistics was used or could be used.

5. Give the standard deviation for the mean and median column. Compare these and be sure to identify which has the least variability?

The performances of a group of interns are evaluated by their supervisors at the end of their internships.

Question 4: The mode is the most frequently occurring value in a set of data so here the mode is 178 so the answer is e.

Short Answer Writing Assignment – Both the calculated binomial probabilities and the descriptive statistics from the class database will be used to answer the following questions.

3. In one elementary school, 200 students are tested on the subject of Math and English. The table below shows the mean and standard deviation for each subject.

2. For the following set of scores, fill in the cells. The mean is 74.13 and the standard deviation is 9.98.

Based on the given sample of student test scores of 50, 60, 74, 83, 83, 90, 90, 92, and 95 after rearranging them from least to greatest. As the mean is based on the average of sum, the average of this sample is 79.67 or 80. The mode refers to numbers that appear the most in a sequence and in this case 83 and 90 both appear twice. Range calculates the difference between the largest and smallest number, which are 95 and 50 which have a difference of 45. The variance is the difference between the sum of squares divided by the sample size, which is the number in the sample minus one (Hansen & Myers, 2012), meaning it takes each number of the set and subtracts
