Statistics in Research Tool for designing research, analyzing data, drawing conclusions. Reduces raw data for readability and further analysis. Descriptive Statistics: Develops indices from raw data. Inferential Statistics (Statistical Analysis): Generalization from samples to population; estimation of parameters, hypothesis testing. Important Statistical Measures Measures of Central Tendency: Arithmetic mean, median, mode (also geometric mean, harmonic mean). Measures of Dispersion: Variance, standard deviation ($\sigma$), mean deviation, range. Measures of Asymmetry (Skewness): Indicates distortion of distribution curve. Measures of Relationship: Correlation, regression. Other Measures: Kurtosis (peakedness of curve). Measures of Dispersion Mean Deviation: Average of the absolute deviations from a central value (mean, median, mode). Calculated as: $\frac{\sum |X_i - \bar{X}|}{N}$ (for population) or $\frac{\sum |X_i - \bar{X}|}{n}$ (for sample) Coefficient of mean deviation: $\frac{\text{Mean Deviation}}{\text{Average}}$ Considers all items, but not amenable to algebraic processes. Standard Deviation ($\sigma$): Square-root of the average of squares of deviations from the arithmetic mean. Calculated as: $\sigma = \sqrt{\frac{\sum (X_i - \bar{X})^2}{N}}$ or $\sigma = \sqrt{\frac{\sum f_i (X_i - \bar{X})^2}{N}}$ Coefficient of Standard Deviation: $\frac{\sigma}{\bar{X}}$ Coefficient of Variation: $\frac{\sigma}{\bar{X}} \times 100$ Variance: $\sigma^2$ (square of standard deviation). Widely used, amenable to mathematical manipulation, less affected by sampling fluctuations. Measures of Asymmetry (Skewness) Describes distortion of a distribution curve from symmetry. Symmetrical Distribution: Normal curve, bell-shaped, $\text{Mean} = \text{Median} = \text{Mode}$. Positive Skewness: Curve distorted to the right, $\text{Mode} Negative Skewness: Curve distorted to the left, $\text{Mean} Significance: Helps understand series formation and curve shape (normal or otherwise). Kurtosis: Measures peakedness of a curve. Mesokurtic: Normal curve. Leptokurtic: More peaked than normal. Platykurtic: Flatter than normal. Measures of Relationship Used for bivariate (two variables) or multivariate (more than two variables) populations. Addresses: Existence and degree of association/correlation. Existence, degree, and direction of cause-and-effect relationship. Correlation technique: Answers question 1. Regression technique: Answers question 2. In Case of Bivariate Population Correlation: Cross Tabulation: Classifies variables into categories, then cross-classifies to find interactions (symmetrical, reciprocal, asymmetrical). Useful for nominal data. Charles Spearman’s Coefficient of Correlation (Rank Correlation): Measures correlation between two variables with ordinal data (ranks). Formula: $R = 1 - \frac{6 \sum d_i^2}{n(n^2 - 1)}$ where $d_i$ is difference in ranks, $n$ is number of pairs. Non-parametric technique. Karl Pearson’s Coefficient of Correlation (Simple Correlation): Most widely used. Assumptions: Linear relationship, causal relationship (one independent, one dependent), normal distribution. Formula: $r = \frac{n \sum XY - (\sum X)(\sum Y)}{\sqrt{[n \sum X^2 - (\sum X)^2][n \sum Y^2 - (\sum Y)^2]}}$ Value of $r$ is between $\pm 1$. Positive $r$: Positive correlation (variables change in same direction). Negative $r$: Negative correlation (variables change in opposite directions). $r=0$: No association. $r=\pm 1$: Perfect correlation. Cause and Effect Relationship: Simple Regression Analysis: Determines statistical relationship between two variables (one independent X, one dependent Y). Basic relationship: $Y = a + bX + e$ (linear regression equation, where $a$ is intercept, $b$ is slope, $e$ is error term). In Case of Multivariate Population Correlation: Coefficient of Multiple Correlation: Measures relationship between one dependent variable and two or more independent variables. Coefficient of Partial Correlation: Measures correlation between two variables, controlling for the effect of one or more other variables. Cause and Effect Relationship: Multiple Regression Equations: Describes relationship with two or more independent variables. Equation form (for two independent variables): $Y = a + b_1X_1 + b_2X_2$ Multicollinearity: High correlation between independent variables, making regression coefficients less reliable. Careful variable selection needed. Association in Case of Attributes When data is based on attributes (e.g., inoculated vs. not, suffered smallpox vs. not). Interest is in knowing if attributes are associated (e.g., inoculation and immunity). Attributes are associated if they appear together in a greater proportion than expected by chance.
