Urgent Statistics Analysis for 2nd Year

1) Comprehensive analysis of (at least) one qualitative variable in the population
• Frequency distribution
• Relative frequency distribution
• Cumulative frequency distribution
• Bar graph + Pie chart

2) Comprehensive analysis of (at least) one quantitative variable in the population
• Frequency distribution (for example: with intervals)
• Relative frequency distribution
• Cumulative frequency distribution
• Histogram + Pie chart
• Measures of center: Mean, Median, Mode, Quartiles
• (Percentiles – optionally)
• Measures of dispersion: Range, Interquartile range, Standard deviation, Quartile deviation, Coefficients of variation
• Box-plot for 5 statistics summary + typical area of variation
• Measures of skewness and kurtosis (only from the software STATISTICA)

You can prepare also comparative analysis for the same variable by groups – optionally.

3) Comprehensive analysis of correlation and regression – optionally
• Correlation distribution
• Scatter plot
• Pearson correlation coefficient, coefficient of determination
• Full regression model – linear theoretical function + standard errors, interpretation of the slope + measure of fitting

4) At least one point and interval estimation for the population mean
• Margin error, standard error, and relative error + graph
• You can prepare estimation for the same parameter by groups – optionally.
• You can estimate population standard deviation as well – optionally.

5) At least one hypothesis testing for one population mean
• Hypothesis testing for two population means – optionally.

6) Nonparametric hypotheses – optionally
• Test for normality or
• Chi-square test of independence
