Statistics and probability

Answer the following activities.

Set B: The following frequency distribution table shows the scores of 40 students in their 107-item Final Examination in Guidance and Counseling. Class Class Frequency Class Deviation Interval Boundaries (0 Frequency Mark (mp) fmp (d) Measures of Centrali Problem Set Points S stem LONG EXAM #1 Activit 8 Points System 3 point for each correct column (0 point for a single mistake in the column) Deviation Mean 10 points for each correct Median measures of centrality with correct computation Provisions for Mean, Median, and Mode Indicators 1 point for each correct measures of centrality without/wrong computation; 0.5 point for each measure of centrality with computation but wrong answer; and 0 oint for no answer and no com utation.

(1 point each) A. Class Boundaries D. Frequency Distribution G. Ranking B. Class Mark E. Mean H. Raw Score C. Descriptive Statistics F. Mode |. Research Data 1. It is the midpoint of a class interval. 2. It is the average of a group of scores. 3. It is dened as the score occurring the most number of times. 4. These are pieces of information that are collected during a study. 5. It is the branch of statistics which involves tabulating, depicting and describing the collected data. 6. It is the organization of numerical data into different classes with their corresponding frequencies in a tabular form. 7. It is another way of organizing the scores described as a relative arrangement in a series according to magnitude from highest to lowest, or vice versa. B. True or False. Decide whether the following pair of statements are true or false. Write the letter of the correct answer on the space provided. Refer to the choices below. (2 points each) A. Both statements are true. C. Only the second statement is true. B. Onl the rst statement is true. D. Both statements are false. 8. The univariate analysis involves the examination across cases of two variables at a time. Frequency distribution and ranking are used to describe a single variable. 9. It is difcult to nd out the substantial meaning in the set of raw scores. Raw scores are collected scores that have been arranged numerically. 10. The deviation is the difference between the average of a group of numbers and a particular number in that group. In a frequency distribution. the deviation is computed by dividing the population into two. 11. In a test scores of 35. 42, 32. 36, 37, 31. 40, 29, 36, 45, 36, 32, 28, 36, 41, the median is 36. The median is the same as the arithmetic mean. VII. Reflection In a real situation and research survey process, how do measures of centrality work? How do descriptive statistics improve the reporting of research data? Write your reflection below. (9 points) Page11of11
