题目如何有效的抑制校园霸凌事件的发生关键词青少年心理假设检验概率分布拟合主成分分析摘要:随着科学技术的飞速发展和互联网的普及,各种信息的传播速度极为迅速,给青少年带来了许多问题。基于这样的背景,本文以附件中的数据为基础,运用多种方法,如概率拟合法、主成分分析法、假设检验法,根据各个问题的要求建立不同年龄段青少年心理状况模型,提出抑制校园霸凌事件发生的策略。针对问题一,利用概率分布拟合方法建立数学模型,从而获得青少年心理状态随年龄改变的变化趋势,并揭示青少年在不同年龄下心理状态的差异性。具体步骤如下:本文首先对题目提供的部分数据进行转换,将A赋为1,B赋为0,同时令正向数值为正,负向数值为负,将三个因变量进行量化处理;然后用Excel软件得出各个年龄段量化后的均值和方差;最后通过MATLAB进行概率分布拟合得出分布图,以获得年龄与青少年心理状态的关系。针对问题二,本文通过主成分分析法建立模型,借助于正交变换,分析影响青少年心理状态的第一主分和第二主分,并揭示不同年龄的青少年心理状态不稳定的原因。具体步骤如下:首先,为了减小数据的差异,本文将提供的数据转换成最大值为1,最小值为0,其它数据标准化为0-1之间;接着采用主元分析法,对不同年龄段青少年的心理影响因素建立PCA模型,根据模型得出主要的影响因素,针对性的给出解决策略。同时,本文在最后进行了模型的优缺点评价。针对本次对青少年的潜在心理和年龄的关系,附上研究分析报告,阐述不同年龄心理状态差异和影响青少年心理的主要因素,对解决校园霸凌行为提供合理意见。英文摘要AbstractWiththerapiddevelopmentofscienceandtechnologyandthepopularityoftheInternet,avarietyofveryfastspeedofinformationdissemination,whichbroughtmanyproblemstoteenagers.Basedonthisbackground,thispaperbasedonthedataintheannex,usingavarietyofmethods,suchastheprobabilityoffitting,principalcomponentanalysis,hypothesistestingmethods,theestablishmentofdifferentagesadolescentmentalhealthmodelinaccordancewiththerequirementsofthevariousissuesraisedinhibitioncampuspolicyincidentsofbullying.Forquestionone,usingprobabilitydistributionfittingmethodstoobtainachangeofadolescentmentalstatuschangeswithageandrevealadolescentmentalstatedifferentagedifference.Specificstepsareasfollows:Firstly,someofthedataprovidedonthesubjectofconversion,Awillbeassignedto1,Bisassigned0,andmakethreethedependentvariablequantized;thencomeallagesquantizedmeanandvarianceusingExcelsoftware;Finally,MATLABfittingprobabilitydistributionsderiveddistribution,inordertoobtaintherelationshipbetweenageandyouthmentalstate.Forthesecondquestion,inthispaper,modeledbyprincipalcomponentanalysis,bymeansofanorthogonaltransformtoanalyzetheimpactofadolescentmentalstateofthefirstmainpointsandthesecondmaindivision,andrevealsthepsychologicalstateofadolescentsagescauseofinstability.Specificstepsareasfollows:First,inordertoreducethedifferencebythedata,convertsthedatasubjecttoprovidethemaximumvalueis1,theminimumvalueis0,otherdatawerenormalizedtobetween0-1;thenusingprincipalcomponentanalysisofdifferentpsychologicalfactorsofadolescentsagesestablishPCLmodel,themainfactorsderivedfromthemodel,targetedtogiveasolutionstrategy.Meanwhile,thispapercarriedouttheadvantagesanddisadvantagesinthefinalevaluationmodel.Forthisrelationshipbetweenyoungpeopleandthepotentialpsychologicalage,accompaniedbyresearchandanalysisreportoutliningthestatusofdifferentagespsychologicaldifferencesandthemainfactorsaffectingadolescentpsychology,toaddressbullyingbehaviorprovidesreasonableopinion.目录一、问题重述...............................................................................................................1二、背景知识...............................................................................................................11.校园霸凌........................................................................................................................12.校园霸凌行为的原因分析............................................................................................22.1霸凌者的心理因素.............................................................................................22.2受害者的心理因素.............................................................................................23.显著性水平....................................................................................................................24.主成分分析....................................................................................................................2三、符号说明和模型假设...........................................................................................21.合理性假设:................................................................................................................22.符号说明:....................................................................................................................3四、模型设计分析.......................................................................................................3五、数值计算及有效值分析.......................................................................................5六、模型推广与评价.................................................................................................126.1.模型的优点..............................................................................................................126.2.模型的缺点..............................................................................................................13七、分析报告.............................................................................................................13八、参考文献.............................................................................................................14九、附录.....................................................................................................................141一、问题重述近年来,我国发生的多起校园霸凌事件在媒体的报道下引发了许多国人的关注.霸凌事件对学生身体和精神上的影响极为严重而长远的,因此对于这些情况我们应该给予高度重的重视.霸凌是各种形式校园暴力中的一种,从某种意义上说,也是危害程度较高的一种.不同于偶发的暴力事件,霸凌行为通常伴随着肉体与精神的双重伤害,并且这种伤害通常会持续很长时间,有时可能会对受害者的心灵产生终身创伤.如果没有受到专业的心理引导,受害者有可能转变为报复
