Conduct hypothesis testing to find significance of results, the p – value associated with each predictor variable and effect size to determine practical significance of results.

SIMULATE AN EMPIRICAL STUDY

The Impact lower socio economic status delay cognitive development in language acquisition

Methodology:

Recruited 600 participants

Age 5 – 7 year olds

300 from Higher Socio economic and 300 from Lower Socio economic backgrounds

With exclusion we were left with 300 participants

Lower socio economic n = 150 (70 boys and 80 girls)

Higher socioeconomic n = 150 (64 boys and 86 girls)

Controlling Variables:

• Quality of education
• Availability of resources
• Home environment
• Level of stimulation the child receives

Confounding Variables

• Genetics
• Parents level of education
• Teacher quality
• Cultural background

SES measure:

• Parent Income
• Occupation
• Level of education
• Marital status

We will use CORRELATION DESIGN

We will use MULTIPLE REGRESSION ANALYSIS to handle the confounding variable and find unique contribution of SES to language development

CODING: use 2 Coders to assess the inter – ratter reliability using SPSS

Conduct hypothesis testing to find significance of results, the p – value associated with each predictor variable and effect size to determine practical significance of results.
