Constructing a Qualitative FDT
Ie.
Table 1: Attributes most of the respondents consider in choosing an entertainment hub. Attributes| Frequency| RF|
Accessibility| 6| 27.3|
Affordability| 6| 27.3|
Parking Space| 5| 22.7|
Crowd| 5| 22.7|
Total| 22| |

Note: The first two tables are always given. Frequency (second table) will be the number of times the stubs/classes (from the example, attributes) appeared in the given information. RF is computed by dividing the frequency by the total, then multiply it by 100. Ie. (6/22)*100=27.3

Interpretation (Use the highest frequencies)
The attributes most of the respondents consider in choosing an entertainment hub are accessibility and affordability.

Quantitative FDT
1. Determine the range. (highest value-lowest value)
Ie. 20-40=16 see the table below.
2. Determine the number of classes.
a. K=N in which N is the number of observation.
i. Example: k=22 k=4.7; round up; k=5
3. Determine the class size.
b. Range/number of classes.
Example: 16/5=3.2; since the data don’t possess any decimals, the answer should be 3 to make it an odd number as well.

Note: if the given data don’t possess decimals, the class size doesn’t have decimals as well. The class size is always an odd number. The number of decimal places depend on the number of decimal places of the given data.

Table 2: Number of times in a month a respondent has entertainment activity. (MS Excel)

Note: 0.5 is only used if the upper and lower limit are whole numbers. But if, for example, it is 4.5 – 6.5, the lower limit will be subtracted by 0.05 while the upper limit will be added with 0.05 and so on and so forth.

CM= (UL+LL)/2

For CF and RCF, click the table for clarification of the equations given.

Interpretation: 4-6 times in a month, the respondents have entertainment...

Data in MINITAB
MINITAB is a powerful, yet user-friendly, data analysis software package. You can launch MINITAB by finding the icon and double clicking on it. After a moment you will see two windows, the Session Window in the top half of the screen and the Worksheet or Data Window in the bottom half.
Data have already been formatted and entered into a MINITAB worksheet. Go to the eCollege Doc sharing site to download this data file. The names of each variable from the survey are in the first row of the Worksheet. This row has a background color of gray to identify it as the variable names. All other rows of the MINITAB Worksheet represent a certain students’ answers to the survey questions. Therefore, the rows are called observations and the columns are called variables. Included with this lab, you will find a code sheet that identifies the correspondence between the variable names and the survey questions.
Complete the answers below and paste the answers from MiniTab below each question. Type your answers to the questions where noted. Therefore, your response to the lab will be this ONE document submitted to the dropbox.

...conceptualized the birth and administered the growth of Arellano University.
This prestigious institution of learning opened in 1938 as the Arellano Law College, named after Cayetano Arellano, first Filipino chief justice. It closed in December 1941 until March 1945 under the Japanese occupation of the Philippines during World War II. At the end of the war, this educational institution reopened in April, 1945 and was renamed as Arellano Colleges offering a two-year preparatory law course and the regular four-year law course, as well as a complete secondary education curriculum.
In June 1945, Arellano Colleges offered a four-year course in education (Bachelor of Science in Education), a two-year teacher training course (Elementary Teacher’s Certificate) and an elementary school training department. Likewise offered were courses in commerce, Foreign Service, and arts and sciences.
A year later, in June 1946, Florentino Cayco, Sr., became the first President of Arellano Colleges. Through his efforts, Arellano Colleges was elevated to, and recognized as, Arellano University on February 22, 1947 by the Department of Education, Culture, and Sports.
It was also in 1947 that the graduate school was organized and authorized to offer a course leading to the degree of Master of Arts in education as a requisite for the grant of university status.
In 1954, Arellano University opened a school of nursing which offered a basic nursing course. In April...

REFLECTION
The first thing that puffs in my mind when I heard the word STATISTIC is that it was a very hard subject because it is another branch of mathematics that will make my head or brain bleed of thinking of how I will handle it. I have learned that statistic is a branch of mathematics concerned with the study of information that is expressed in numbers, for example information about the number of times something happens. As I examined on what the statement says, the phrase “number of times something happens” really caught my attention because my subconscious says “here we go again the non-stop solving, analyzing of problems” and I was right. This course of basic statistic has provided me with the analytical skills to crunch numerical data and to make inference from it. At first I thought that I will be alright all along with this subject but it seems that just some part of it maybe it is because I don’t pay much of my attention to it but I have learned many things. I have learned my lesson.
During our every session in this subject before having our midterm examination I really had hard and bad times in coping up with this subject. When we have our very first quiz I thought that I would fail it but it did not happen but after that, my next quizzes I have taken I failed. I was always feeling down when in every quiz I failed because even though I don’t like this...

...techniques.
Firstly we look at data analysis. This approach starts with data that are manipulated or processed
into information that is valuable to decision making. The processing and manipulation of raw
data into meaningful information are the heart of data analysis. Data analysis includes data
description, data inference, the search for relationships in data and dealing with uncertainty
which in turn includes measuring uncertainty and modelling uncertainty explicitly.
In addition to data analysis, other decision making techniques are discussed. These techniques
include decision analysis, project scheduling and network models.
Chapter 1 illustrates a number of ways to summarise the information in data sets, also known as
descriptive statistics. It includes graphical and tabular summaries, as well as summary measures
such as means, medians and standard deviations.
Uncertainty is a key aspect of most business problems. To deal with uncertainty, we need a basic
understanding of probability. Chapter 2 covers basic rules of probability and in Chapter 3 we
discuss the important concept of probability distributions in some generality.
In Chapter 4 we discuss statistical inference (estimation), where the basic problem is to estimate
one or more characteristics of a population. Since it is too expensive to obtain the population
information, we instead select a sample from the population and then use the information in the
sample to infer the...

...three routes in the sample. He divides them into different sub-groups such as satisfaction, refreshments and departure time and then selects proportionally to highlight specific subgroup within the population. The reasons why Mr Kwok used this sampling method are that the cost per observation in the survey may be reduced and it also enables to increase the accuracy at a given cost.

...compliments the regular mathematics and therefore both are tested in primary schools. Mathematics is the written application of operation. It teaches students to think clearly, reason well and strategize effectively. Mental Mathematics is the ability to utilise mathematical skills to solve problems mentally. The marks scored by pupils generate statistics which are used by teachers to analyse a student’s performance and development of theories to explain the differences in performance.
The Standard 3 class is where the transition from junior to senior level occurs where teachers expect the transference of concrete to abstract thinking would have occurred.
A common theory by many primary school teachers is ‘Students perform better in Mathematics than Mental math. Mental math is something that has to be developed and involves critical thinking. Mental math requires quick thinking and the student must solve the problem in their minds whereas in regular mathematics, the problem can be solved visually. Therefore, teachers should take these factors into consideration while testing and marking students in these areas.’
In this study, the statistics of 30 students of a standard 3 class of San Fernando Boys’ Government School will be analysed to determine the truth of this theory.
