Rangskik die data van kleinste na grootste, of van grootste na kleinste.
Tel die hoeveelheid datawaardes in die datastel.
Deel die hoeveelheid datawaardes deur vier. Die resultaat is dan die hoeveelheid datawaardes per groep.
Bepaal die datawaardes wat ooreenstem met die eerste, tweede en derde kwartiele deur die hoeveelheid datawaardes per kwartiel te gebruik.

Die eerste kwartiel verskyn tussen dataposisies 3 en 4 en dit is die gemiddeld van datawaardes 5 en 8. Die tweede kwartiel verskyn tussen posisies 6 en 7 en dit is die gemiddeld van datawaardes 12 en 24. Die derde kwartiel verskyn tussen posisies 9 en 10 en dit is die gemiddeld van die datawaardes 28 en 30.
Die eerste kwartiel = 6,5. (

Die tweede kwartiel = 18. (

Die derde kwartiel = 29. (

Interkwartielvariasiewydte
Interkwartielvariasiewydte
Die interkwartielvariasiewydte is 'n maatstaf wat inligting verskaf aangaande die verspreiding van 'n datastel. Dit word bereken deur die eerste kwartiel van die derde kwartiel af te trek en dit gee die variasiewydte van die middelste helfte van die datastel. Dit sny dan basies die laagste en hoogste kwartiele af, naamlik
.
Die half-interkwartielvariasiewydte is helfte van die interkwartielvariasiewydte, naamlik
'n Klas van 12 studente skryf 'n toets en na die toets lyk die punte soos volg: 20, 39, 40, 43, 43, 46, 53, 58, 63, 70, 75, 91. Vind die variasiewydte, kwartiele en die interkwartielvariasiewydte.

Die variasiewydte = 91 - 20 = 71. Dit sê vir ons dat die punte redelik wyd versprei is.

Die kwartiele is 41,5, 49,5 en 66,5. Hierdie kwartiele sê vir ons dat 25
van die punte is minder as 41,5; 50
van die punte is minder as 49,5 en 75
van die punte is minder as 66,5. Hulle sê ook vir ons dat 50
van die punte lê tussen 41,5 en 66,5.
Die interkwartielvariasiewydte = 66,5 - 41,5 = 25. Dit sê vir ons dat die wydte van die middelste 50
van die datawaardes is 25.
Die half-interkwartielvariasiewydte =
= 12,5

Persentiele
Persentiele is die 99 datawaardes wat 'n datastel in 100 groepe deel.
Die berekening van persentiele is identies met die berekening van kwartiele, behalwe dat die doel is om die datastel in 100 groepe te deel in plaas van 4 groepe soos by kwartiele.
Communication is effective because it allows individuals to share ideas, thoughts, and information with others.
effective communication can lead to improved outcomes in various settings, including personal relationships, business environments, and educational settings. By communicating effectively, individuals can negotiate effectively, solve problems collaboratively, and work towards common goals.

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills
hello. autism is a umbrella term. autistic kids have different disorder overlapping. for example. a kid may show symptoms of ADHD and also learning disabilities.
before treatment please make sure the kid doesn't have physical disabilities like hearing..vision..speech problem. sometimes these

continue..
sometimes due to these physical problems..the diagnosis may be misdiagnosed.
treatment for autism.
well it depends on the severity.
since autistic kids have problems in communicating and adopting to the environment.. it's best to expose the child in situations where the child
Jharna
child interact with other kids under doc supervision.
play therapy.
speech therapy.
Engaging in different activities that activate most parts of the brain.. like drawing..painting. matching color board game.
string and beads game.
the more you interact with the child the more effective
Jharna
results you'll get..
please consult a therapist to know what suits best on your child.
and last as a parent. I know sometimes it's overwhelming to guide a special kid.
but trust the process and be strong and patient as a parent.
