5. 5. 3.0 Objectives of the survey The objective of the survey is to find the number of the books read by the IPTHOstudents in a week. From these topics, I can identify the types of books that studentslike to read and how they get the books. In this survey, there are a few number ofinformation that I can gain. 1. I can get the average number of the books that had been read by the students. 2. I can get the information where students get the books to read. 3. I can identify the types of books that students like to read.
6. 6. 4.0 Importance of the survey The importance of this survey to me is I can identify the number of the booksread by the IPTHO students in a week. Besides that, I can get the types of books thatthey like to read and how they get the book. Here, I can see the percentage of studentsthrough the bar chart, pie chart and the histogram. From this survey also I can fulfill thequestion for the basic mathematics coursework. This survey is important for IPTHO because the administration department haveto fulfill the facilities needed by the student in the hostel. If the number of the studentsthat like to read the books is more than the number of students doesn’t like to read, it ispossible for administration to increase the number of book in the library. So, thestudents will always come to library and read many books in a week. The student will befeeling satisfied and can get much knowledge if the facility is fine. Besides that, the success of the student is depending on the time management.If the library doesn’t have many books to read, they will feel boring and don’t like to readanymore. When this is happen, the time table has been interrupted and the activitiesunwell done.5.0 Limitation of the survey The limitation of this survey is 40 people. From 40 people, it is divided into 2,which is 20 for male students and 20 for female students. The 40 respondent takenamong the students in IPTHO. This survey took place in IPTHO.
7. 7. 6.0 Definition of term6.1 StatisticsIs a mathematical science pertaining to the collection, analysis, interpretation orexplanation, and presentation of data. It is applicable to a wide variety of academicdisciplines, from the natural and social sciences to the humanities, government andbusiness.6.2 Statistical populationIs a set of entities concerning which statistical inferences are to be drawn, often basedon a random sample taken from the population6.3 SkewnessIs a measure of the asymmetry of the probability distribution of a real-valued randomvariable.6.4 Data set (or dataset)Is a collection of data, usually presented in tabular form. Each column represents aparticular variable. Each row corresponds to a given member of the data set in question.It lists values for each of the variables, such as height and weight of an object or valuesof random numbers. Each value is known as a datum. The data set may comprise datafor one or more members, corresponding to the number of rows.
8. 8. 6.5 Datarefers to a collection of organized information, usually the result of experience,observation or experiment, other information within a computer system, or a set ofpremises. This may consist of numbers, words, or images, particularly asmeasurements or observations of a set of variables6.6 Sample sizeOf a statistical sample is the number of observations that constitute it. It is typicallydenoted n, a positive integer (natural number). Typically, all else being equal, a largersample size leads to increased precision in estimates of various properties of thepopulation. This can be seen in such statistical rules as the law of large numbers andthe central limit theorem. Repeated measurements and replication of independentsamples are often required in measurement and experiments to reach a desiredprecision.6.7 SamplingIs that part of statistical practice concerned with the selection of individual observationsintended to yield some knowledge about a population of concern, especially for thepurposes of statistical inference. Each observation measures one or more properties(weight, location, etc.) of an observable entity enumerated to distinguish objects orindividuals. Survey weights often need to be applied to the data to adjust for the sampledesign
9. 9. 6.8 Frequencyof an event i is the number ni of times the event occurred in the experiment or the study.These frequencies are often graphically represented in histograms. We speak ofabsolute frequencies, when the counts ni themselves are given and of (relative)frequencies.6.9 ModeIs the value that occurs the most frequently in a data set or a probability distribution. Insome fields, notably education, sample data are often called scores, and the samplemode is known as the modal score.6.10 ObservationIs either an activity of a living being (such as a human), which senses and assimilatesthe knowledge of a phenomenon, or the recording of data using instruments. The termmay also refer to any datum collected during this activity.6.11 Medianis described as the number separating the higher half of a sample, a population, or aprobability distribution, from the lower half. The median of a finite list of numbers can befound by arranging all the observations from lowest value to highest value and pickingthe middle one.
