Key Formulas You Need to Know
To perform well, focus on mastering the following formulas commonly used in problem-solving scenarios:
- Standard Deviation (σ):
σ = √(Σ(xi – μ)² / N)
Where xi is each value, μ is the mean, and N is the number of data points. This formula is crucial for measuring the spread of a data set.
- Variance (σ²):
σ² = Σ(xi – μ)² / N
Variance is the square of the standard deviation and measures data dispersion.
- Confidence Interval (CI):
CI = x̄ ± Z(σ/√n)
Where x̄ is the sample mean, Z is the Z-score for a given confidence level, σ is the standard deviation, and n is the sample size.
- T-test for Mean:
t = (x̄ – μ) / (s / √n)
Use this formula for testing if the sample mean is significantly different from the population mean.
- Chi-Square Test:
χ² = Σ((O – E)² / E)
Where O is the observed frequency, and E is the expected frequency. This is used to test relationships between categorical variables.
- Regression Equation:
y = mx + b
This is used to predict the value of a dependent variable y based on the independent variable x, where m is the slope and b is the y-intercept.
- P-value:
P-value = Probability of obtaining the observed result, or something more extreme, under the null hypothesis
A P-value of less than 0.05 often indicates statistical significance.
Familiarity with these formulas is key to answering questions accurately and efficiently. Ensure you practice solving problems using these formulas to gain confidence in applying them during your assessment.
