3. Introduction
• Social and emotional developement is one of the key factors
that determine cognitive development.
• Key factor for future school achievement
• Important to consider in educational policies
• Also affect communication skills which are key for healthy
relationships and a satisfying interaction with people
• Happiness is linked to social interaction so understanding
social and emotional development is crucial

targets AUI students.

4. What is Social and Emotional
Development?
• We can’t talk about emotional development without
associating it with social development because the emotional
shaping of our personalities occurs within a social construct
• It refers to a child’s capacity for self-confidence,trust,empathy
as well as the capacity to develop competencies in language
usage and cognitive curiosity.

Probabilities
P(High Rank in Family)= 0,55
P(High Responsibility)= 0,36
P(Low Responsibility)= 0.18

12. Linear Regression
• Dependent variable : Emotional Stability
• Independent variable : Age Rank

13. Results of Regression Analysis
on Excel : Family Rank versus
Emotional Stability

14. Output Interpretation
• Y= β0+β1 x1= 0.09+0.49x1
• An increase of one unit in the age rank causes an increase of
0.49 in emotional stability.

15. Results of Regression Analysis
on Excel : Family Rank versus
Responsibilities

16. Output Interpretation
• Y= β0+β1 x1= 0.20-0.54x1
• An increase of one unit in the age rank causes a decrease of
0.54 in responsibilities.

17. Hypothesis Testing 1 : Age
Rank and Emotional Stability
• Null Hypothesis H0 : Age rank has no effect on emotional
stability
• Alternate Hypothesis H1 : The higehr the age rank the higher
the emotional stability.
• Types of tests used (2) :
• t-Test: Two-Sample Assuming Unequal Variances
• F-Test Two-Sample for Variances

18. t-Test: Two-Sample Assuming
Unequal Variances

19. F-Test Two-Sample for Variances

20. Hypothesis Testing 2 : Age
Rank and Responsability
• Null Hypothesis H0 : Age rank has no effect on amount of
responsability.
• Alternate Hypothesis H1 : Age rank has an impact on amount
of responsability.

21. t-Test: Two-Sample Assuming
Unequal Variances

22. F-Test Two-Sample for Variances

23. General Discussion
• Factors that might cause the effect of age rank on emotional
stability :
• Feelings of jealousy
• Social and Financial Pressure on family upon arrival of newborns

24. Conclusion
• Survey conducted on 90 AUI Students about Emotional
Stability
• Descriptive statistics techniques were used in order to analyze
the data firsthand.
• Inferential statistics tools were used to dig deeper and explore
relationships between variables (regression) and test
hypothesis.
• Hypothesis : The higher the ange rank the higher the
emotional stability
• 2/3 of the tests indicated its validity with confidence interval
of 95%
