CHAPTER 2RESEARCH PROBLEMAI{D HYPOTHESIS

Generally, maj ority of the thesis anddissertation writers find difficurty in lookingfor a researchabre probrem. once they have founda researchabl_e problem, Lhey still finddifficulty in stating the specific researchproblem and formul_ating the hypothesis.

It r-s necessary that thesis andcissertation writers should know to choose aresearchabl-e probrem. rf possibre, a researchproblem which possesses the 7M's resources suchas Manpower, Money, Mdterials, Methods,MachJ-nery, Moment of time, and Marketing.Many of the t.heses and dissertations gatherdust in the shelves due to no return ofinvestment at al-l-.

recovery because maj ority of the graduates donot respond to the socioeconomic development ofthe country. Their theSes and dissertationsresults have no return of investment.Moreso, graduates are only trained ondescriptive research. It is a must that

undergraduate and graduate students must betrained both on descriptive and experimentalresearches in order that the Philippines must begreat again.Research Problem

There are five factors to consider to findout if a problem is researchable. Eitst, theproblem is existing in the locality or countrybut no known solution to the problem. Secorzd,the solution to the problem can be answeredusing statistical methods and techniques. Tbj-rd,there are probable solutions but not yet ttsted.Fourth, the occurrence of phenomena requiresscientific investigation to arrive at precisesolution . gifth, serious needs and problems ofthe people where it demands research.

Based on the aforementioned factors, theresearcher can choose a researchable problem.The research problem must be stated clearly andexactly expressed in an interrogative form for"questions have the virtue of posing a problemdirectly." (KerIinger, 1986) .

A good research problem should respond tothe socioeconomic recovery of the country whereinthe research output can be converted into small28

The maj or research problem is "WEIGHTINCREMENT OF MUDCRAB (SCYLLA SERRATA) CULTUREDIN THE FISHPOND USING PELLETS AND BREAD MEAL ASSUPPLEMENTAL FEEDS''

Based on the above maj or -research problem,theSpecificresearchprob}emsareaSfollows:1. What is the mean weight increment of mudcrab(Scy]]aserrata)culturedinthefishpondusing 'Pellets and bread meal- as

The characteristics of a research problemhas acronym of SMART Specific, Measurable,Achievable, Realistic and Time bound- This meansthat a research Problem should be:SPecific- The Problem should bespecifically stated ' For example ' fordes criptive research, "what is the correlationbetweenEng]ishScoreandnumberofhoursof

For experimentaf resea rch, "What is themean weight increment of mudcrab (ScyLLa serrata)cultured in the fishpond using pellets and breadmeal as supplemental feeds ? "Measurable. It is easy to measure by usingresearch instruments, apparatus and equipmentin gathering of data.

For descriptive research, the researchinstrument used in gathering data arequestionnaires, tests, checklists, observationschedules and manv others.For experimental- res earch, the apparatusand equipment used in collecting data on theweight increment of mudcrab ( Scyl-La serrata)cultured in the fishpond using peflets and breadneal as supplemental feeds are weighing scal-e toEet the weight of mudcrab; refractometer,salinity of water; thermometer, temperature ofwater; DO meter, dissolved oxygen of water; andpH meter, acidity of water.Achiewable. The data are achievable by-rsing correct statistical tools to arrive atexact results . For instance, in descriptive:esearch, Pearson product moment coefficient:orreLation is correct statistical tool to thisspeci fic probfem, "What is the correlationbetween scholastic achievements and number ofaours of study in English to freshmen secondary

For experimental- res earch, the appropriatestatistical tool is t-test for this specificproblem, "Is there a significant difference onthe mean weight increment of mudcrab (ScyITaserrata) cultured in the fishpond using pelletsand bread meal as supplemental feeds?" Ifresults show that there is significantdifference on'the mean weight increment of mudcrab(scylLa serrata) cultured in the fishpond usingpellets and bread meal as supplemental' feeds,this means that the mean weight increment ofmudcrab (S. serrata) cultured in the fishpondusing pellets and bread meal as supplementalfeeds really di ffer with each other . I finsignificant difference exist.s, this means thatthe mean weight increment of mudcrab (S. serrata)cultured in the fishpond using pellets and breadmeal as supplemental feeds is almost the same.Realis tic. Real- results are attainedbecause they are gathered scientifically andnot maneuvered.Tj-me bound. Time frame is necessary tnevery activity because the shorter completionof the activitY the better.
