Key Learning: Why is DI important ? - Problem solving/ Decision Making is fundamentally Data Analysis. Types of Sets: - LR - DI - Mixed: DI based LR or LR based DI. Data = Dimension + Variables Dimension = Category. Different angles/ perspective of the data. Variable = Each row/ record of data. Representation of Data: - Table: Most fundamental way of representing data. Any tabular data can be represented in any other form. - Pie chart: Shares/ Composition of something - Line Chart: Growth/ change over a period of time - Bar chart (single/multiple/ horizontal/vertical ): Comparison - Special - Histogram/ spider Interpretation: Highest, lowest, growth, ratio, etc. (asking questions) DI = Data + Interpretation Types of Calculation: - Highest/ Lowest - Comparison of values, shares, ratios. - Average, how many above, how many below. Percentage: - A as a %age of B (%age share) - A % of B (Tax / discount /Growth) - %age more or less. Comparison. - Share of Share : Multiple charts. Growth Rate: - SAGR: Simple Annual Growth Rate. CAGR: Compounded Annual Growth Rate, - AAGR: Average Annual Growth Rate. - Approximation vs Accuracy. Calculations: -Avg - Fraction & Percentage - Approx %age - comparison of fraction - Inc/ dec of fraction: Change in Num, Den, Both Averages (Which method to use depends on: How close the options are) - Kharbuja Katega Saab mein Baateinga (KKSB): Take a value to be avg, find the sum of Excess / Deficit of each, divide among all. (Accurate) - See the higher and lower numbers & cut them (Balancing) - 43:00 - Gadho mein Gadha dalne se Gadha gadha hi rehta hai. (GGGG): If avg is added to avg, avg remains avg. - (Highest + Lowest ) / 2 (Approximate) (High Standard Deviation and skewed data can impact the value: Self analysis) Practice. Practice. Practice. Significant Digits (2 digits ) Somethings have to be accurate & something which can be approximate. Approximate Percentage: - Standard Fractions: 1/ 1 to 1/ 20 & variations: Horizontal & below (MEMORISE by Heart) 34/ 48 - > 17/ 24 1. 16/ 24 > 2 / 3 - > 66.6% 2. 18 / 24 > 3 / 4 - > 75% 3. Difference: 8.33 % Divided by 2 - > 4.15% 4. Add to 66% 5. Answer = 70.13% (Eye Opening Technique) - Adding by constant to Num & Den, fraction will approach towards unity. Smaller fractions(< 1) will increase and larger fractions will decrease(> 1) - SAGR: (End - Start) / (Start * Periods) - CAGR - Compound interest formula - AAGR: Average of individual growth rate. (Approximately close to CAGR)
