  • 1. STATISTICS SURVEY REPORT 1PREPARED BY: 1. Muhammad Saeed 2. MUHAMMAD AAMIR RIAZ 3. Muhammad ImranFACILITATOR: 1 MA’AM RAKHSHANDA SHAHTOPIC: “ESSENTIALITY OF MATHEMATICS”COURSE: BUSSINESS MATHEMATICSDATE : 30TH MAY 2003
  • 2. STATISTICS SURVEY REPORT 2ACKNOWLEDGEMENT: We, Muhammad Imran, Muhammad Aamir Riaz,Muhammad Saeed, worked in a group, to carry out asurvey on “Essentiality Of Mathematics In OurProfessional Life” which is also the requirement of thiscourse, as this survey and the arrangement of data ofthis survey both are very time consuming &overshadowing effort but we thanks Almighty Allahwho empowered us to complete these practical andreport. We would also like to say coordinal thanks andappreciate the memorable behaviour and lovingattitudes of all the students of TIP to whom we havegiven the survey forms and in this regard theircooperation was beyond our expectations and this,helped us a lot in gratifying the data &accomplishment of this report. We wish to elegantly and heartily thank to theinstructor of our course, Ma’am Rakshanda Shah for hiscomplete collaboration and assistance. Responsibility for any sort of errors and exclusionsis certainly our.
  • 3. STATISTICS SURVEY REPORT 3TOPIC:“Evolutionary study for the ignorance and fear of mathematics in designing, management and textile science students.”As it is a very famous saying; “Math is a way for lazy people to learn how to do thing quickly and well.” “It’s a way to have a well organized mind and it will help you to solve all kinds of problems later on in your age”.PURPOSE OF STUDY:Our objective is to find the opinion of students about the essentiality ofmathematics for professional field.My report is concerned with the feed back of students about theessentiality and the interest of mathematics in their professional field.The foremost objective is to compare the interest in mathematicsbetween designing, management and textile science and alsocomparison between those students who likes and those who dislikethe mathematics and their marks in exams.QUESTIONNAIRES:Questionnaires can be most simply defined as apprises of collectingsuch information, from desired individuals groups or organizations,which cannot be easily obtained from direct sources. “OR”The word questionnaires are used most often to describe a method ofgathering information from a sample of individuals. This sample isusually just a fraction of the population being studied.

  • 5. STATISTICS SURVEY REPORT 5 “SOME IMPORTANT DEFINITIONS”DEFINITION OF STATISTICS: Statistics are numerical facts in any field of study. “OR” Statistic deals with techniques or methods for collecting analyzing and drawing conclusions from data.Statistics methods are divided into two categories namely descriptiveand inferential. 2 Descriptive statistics 3 Inferential statisticsDESCRIPTIVE STATISTICS:It deals with the collections classifications summarization andpresentation of data.INFERENTIAL STATISTICS:It deals with the conclusions drawn about a population using the dataof a sample taken from the same population.POPULATION:Population consists of the totality of the observations with which weare concerned.SAMPLE:A sample is a subset of a population.SIMPLE RANDOM SAMPLE:A simple random sample of “n” observations is a sample that is chosenin such a way that very subset of n observations of the population hasthe same probability of being selected.PROBABILITY:A probability is a numeric measure of the likelihood or chance that aparticular event will occur.Symbolically it is written as;
  • 6. STATISTICS SURVEY REPORT 6 n( A) P( A) = n(S )It is further distributed into following ones;1. Binomial 2. Poisson3. Hyper geometric 4. NormalMEASUREMENT OF TENDENCY:Generally we have two types of tendencies; 1. Measures of central tendency 2. Measures of dispersion1. MEASURES OF CENTRAL TENDENCY:It is defined as a single value of the data, which truly represents thewhole data.It is further classified into; i. Arithmetic Mean ii. Geometric Mean iii. Harmonic Mean iv. Median v. ModeARITHMETIC MEAN:It is the most commonly used measure and usually termed as simplemean. “It is defined as the sum of the values divided by the number of values in the raw data.”Here the mean of a sample of n values, is known as sample mean andis denoted by x . n ∑x i x= i =1 nWhereas, if the data is not a sample but the entire population of Nvalues, it is termed as population mean and is denoted by µ. N ∑x i µ= i =1 NWEIGHTED ARITHMETIC MEAN:The mean of a data gives equal importance or weights to each of thevalues of raw data. In some general cases all values in the raw data
  • 7. STATISTICS SURVEY REPORT 7don’t have the same importance. A weighted mean is used to assignany degree of importance to each value of the data by choosingappropriate weights for these values. xw = ∑ w.x ∑wHere, “w” are the weights assigned to the values of data.GEOMETRIC MEAN:Geometric mean is defined only for non-zero positive values. It is thenth root of the product of n values in the data. G = n x1 x2...xKWEIGHTED GEOMETRIC MEAN;If weights are assigned to the values of the data, in this regard we cancalculate the geometric mean. G.M . = Anti log[ ∑ w.log x ] ∑wHARMONIC MEAN:Harmonic mean is defined only for non-zero positive values; it is thereciprocal of mean of reciprocal of values. K H = K 1 ∑i = 1 xiWEIGHTED HARMONIC MEAN:If all values of the data are not equally important, a weightedharmonic mean is calculated after assigning appropriate weights tothe values of the data. H .M . = ∑w w ∑( x )MEDIAN:Median is defined as the middle value of the data when the values arearranged in ascending or descending order. ~ µ=λ+ h ( n − c. f ) f 2
  • 8. STATISTICS SURVEY REPORT 8MEDIAN OF A FREQUENCY DISTRIBUTION:Values of the data in an interval are evenly or uniformly spread inthat interval is known as the median of the frequency distribution. Width of the interval No. of values in the intervalPARTITION VALUES OR QUARTILES:QUARTILES:There are three values, which can divide the arranged data in fourequal parts or quarters. These values are called quartiles. h n Qi = l + ( i − c. f ) f 4DECILES:There are nine values, which can divide the arranged data in ten equalparts. h n Di = l + ( i − c. f ) f 10PERCENTILES:Similarly, the 99 values, which divide the arranged data in 100 equalparts, are called percentiles. h n Pi = l + ( i − c. f ) f 100MODE:Mode is a measure of central tendency generally used when the data isof qualitative nature where the addition (for mean) or arrangement(for median) of values is not possible.It is defined as that category of the attribute, which repeats maximumnumber of times in the data. fm − f 1 Mode = x = l + ( ˆ )×h 2 fm − f 1 − f 2MODE OF A FREQUENCY DISTRIBUTION:In a frequency distribution mode is that value of the variable forwhich the frequency curve takes maximum height.
  • 9. STATISTICS SURVEY REPORT 9A frequency distribution with one mode is called unimodal and withtwo modes is called a bimodal frequency distribution.2. MEASURES OF DISPERSION:The dispersion is defined as the scatter or spread of the values fromone another or from some common values. The method to compute theamount of dispersion present in any data is called “Measures ofDispersion” or “Measures of Variation”.The measures of dispersion are further classified into; i. Range ii. Quartile Deviation iii. Mean Deviation iv. Standard DeviationRANGE:Range is the simple measure of dispersion and is defined as thedifferences between the maximum and minimum values of the data. R = Xmax− XminRange is generally rough and crude measurement as it ignores thevariation among all the values.QUARTILE DEVIATION:The difference between the third and first quartiles is called theinterquartile range and quartile deviation is the half of theinterquartile range and is also known as the semi-interquartile range. Q3 − Q1 Q.D. = 2MEAN DEVIATION:Dispersion can be measured in terms of the quantities that each valueof the data deviates from average value.Mean deviation for ungrouped data; M .D. = ∑| x − x | nMean deviation for grouped data; K ∑f i | xi − x | M .D . = i =1 K ∑f i =1 i
  • 10. STATISTICS SURVEY REPORT 10Hence in this regard it is defined as, sum of absolute deviations frommean divided by the number of values.STANDARD DEVIATION:Standard Deviation is the most widely used measure of dispersion andis defined as the positive square root of a quantity called variance.Standard deviation for sample-ungrouped data; n ∑ (x − x)i 2 s= i =1 n −1Standard deviation for population-ungrouped data; N ∑(x − µ) i 2 σ = i =1 NStandard deviation for sample-grouped data; K K n∑ f x − (∑ fi xi )2 2 i i s= i =1 i =1 n(n −1)Standard deviation for population-grouped data; K K N∑ f x − (∑ fi xi )2 2 i i σ= i =1 i =1 N

  • 27. STATISTICS SURVEY REPORT 27CONCLUSION:By the comparison of Management, Sciences and Designingfaculties, we conclude that all the departments agreed onthe intense importance and inimitable significance ofMathematics and think it is essential for all of them, whichwe think is not expected as our suppositions about Designingdepartment. It is a common fact, students having harder field of studyavoid mathematics but here at T.I.P majority of Designingstudents think that mathematics is hard but on the otherhand, majority of them has showed their interests to learnMathematics and their proportion is slightly higher then theSciences students. Here it is interesting thing to discuss isthat majority of Designing students also thinks thatMathematics is easier as compare to their designing and artssubject, hence on this basis they are interested to learnMathematics. However, al lot of students in all of thefaculties give the response that mathematics is a veryinteresting and easy subject but at TIP they are notinterested to learn it more, may be the reason is that theythink it is not compatible to their profession or don’t helpthem in their profession.Here a very remarkable and significant matter of discussionis that majority of students don’t want to learn theMathematics on the teaching methods and teaching criteriaof their Instructors. Some of the students think that theyhave good teachers and only on this basis they considerMathematics interesting and want to learn it while on heother student same ratio of students opposed this object.
  • 28. STATISTICS SURVEY REPORT 28RECOMMENDATIONS: After getting the results of the analysis of our survey we recommend that Mathematics should be taken as “Applied/Associated ” subject in every discipline of textiles. For the students of the basic classes of textiles, the quality teachers should be provided so that they could develop a good interest in Mathematics in them. If the parents have low interest in Mathematics and they find it hard to study, then they should keep their views to themselves and should allow their children to choose their field of interest themselves. There should be a few courses of “Mathematical Modeling”.
