The procedures of #factor analysis


ተለዋዋጮች በምክንያቶች ላይ ወደ ኋላ የሚመለሱበትን የምክንያቶች እና የድግግሞሽ ጥምርታ እሴቶችን ያገኛሉ። እነዚህ የድግግሞሽ ቅንጅቶች the psychological and factor-analysis ጽሑፍ እንደ factore loding ወይም ፋክተር cofficent ይጠቀሳሉ።

for the clarity of subject matter, factor analysis always used before doing regression analysis. even some time factor analysis was use before even checking reliability of the instrument you are using for studying a particular phenomenon. It is a requirement in factor analysis and in regression to use continuous data.

🤬🧶NORMALITY TEST ??

Testing for Normality #using SPSS Statistics

is a# prerequisite for many statistical tests because normal data is an underlying assumption in parametric testing. There are two main methods of assessing normality: graphically and numerically.

Propensity score matching #(የፕሮፔንሲቲ ነጥብ ማዛመድ) (PSM)
it is a quasi-experimental method (በቁጥር-የሙከራ ዘዴ ነው) in which the researcher uses statistical techniques to construct an artificial control group by matching each treated unit with a non-treated unit of similar characteristics. Using these matches, the researcher can estimate the impact of an intervention.

E.g.200 ተማሪዎች ከአማካሪ (100) እና ከግለሰብ (100) ጋር ጥናት ያደረጉ ተማሪዎች።
ጥያቄዎች፡ በምርምር ጥራታቸው እና አቀራረባቸው ላይ በጣም ጥሩ የሆነው የትኛው ነው?

Therefor, we use treated-for those who are using consultant (1) and control group= without consultant (0)=
ከዚያ PSM እንጠቀማለን:

#የሙከራ ምርምር /Experimental Study/

ይህ እይነቱ ምርምር አንድን ሁኔታ በሙከራ አረጋግጦ ማየትን የሚመለከት ምርምር
ነው፡፡ ለምሳሌ #በአፀደ ሕፃናት ፕሮግራም ውስጥ ካለፉና በቀጥታ ከቤታቸው ወደ አንደኛ
ክፍል ከገቡ ሕፃናት ሒሣብን፣ አማርኛን፣ ሣይንስን፣ ወይም ሌላ ትምህርት የትኞቹ
በይበልጥ እንደሚከታተሉ ሕፃናቱን (using correlated study) ለይቶ በጥንቃቄ በመከታተል ማወቅ ይቻላል፡፡
ጥናቱ ተጀምሮ እስኪጠናቀቅ መረጃዎችን በጥንቃቄ መያዙ ለውጤቱ ትክክለኛነት እጅግ
በጣም ወሳኝ ነው፡፡
#ለምሳሌ: ከትምህርት ቤት ውጪ ተጨማሪ እገዛ ማግኘት አለማግኘታቸውን፣ የቤተሰብ
ልዩነት አለመኖሩንና የቤተሰብ የኑሮ ሁኔታ ልዩነት ሁሉ መጤን ያለባቸው ነገሮች
ናቸው፡፡ Because,Experimental studies are ones where researchers introduce an intervention and study the effects. Experimental studies are usually randomized, meaning the subjects are grouped by chance. Randomized controlled trial (RCT): Eligible course attending by children's are randomly assigned to one of two or more groups. https://t.me/mamaker
