Data Analytics

80% of people who start learning data analytics never land a job. Not because they lack skill but because they get stuck in "preparation mode." I was almost one of them. I spent months: -Taking courses. -Watching YouTube tutorials. -Practicing SQL and Power BI. But when it came time to publish a project or apply for jobs I hesitated. “I need to learn more first.” “My portfolio isn’t ready.” “Maybe next month.” Sound familiar? You don’t need more knowledge you need more execution. Data analysts who build & share projects are 3X more likely to get hired. The best analysts aren’t the smartest. They’re the ones who take action. -They publish dashboards, even if they aren’t perfect. -They post case studies, even when they feel like imposters. -They apply for jobs before they "feel ready" Stop overthinking. Pick a dataset, build something, and share it today. One messy project is worth more than 100 courses you never use.

Power BI DAX Cheatsheet 🚀 1️⃣ Basics of DAX (Data Analysis Expressions) DAX is used to create custom calculations in Power BI. It works with tables and columns, not individual cells. Functions in DAX are similar to Excel but optimized for relational data. 2️⃣ Aggregation Functions SUM(ColumnName): Adds all values in a column. AVERAGE(ColumnName): Finds the mean of values. MIN(ColumnName): Returns the smallest value. MAX(ColumnName): Returns the largest value. COUNT(ColumnName): Counts non-empty values. COUNTROWS(TableName): Counts rows in a table. 3️⃣ Logical Functions IF(condition, result_if_true, result_if_false): Conditional statement. SWITCH(expression, value1, result1, value2, result2, default): Alternative to nested IF. AND(condition1, condition2): Returns TRUE if both conditions are met. OR(condition1, condition2): Returns TRUE if either condition is met. 4️⃣ Time Intelligence Functions TODAY(): Returns the current date. YEAR(TODAY()): Extracts the year from a date. TOTALYTD(SUM(Sales[Amount]), Date[Date]): Year-to-date total. SAMEPERIODLASTYEAR(Date[Date]): Returns values from the same period last year. DATEADD(Date[Date], -1, MONTH): Shifts dates by a specified interval. 5️⃣ Filtering Functions FILTER(Table, Condition): Returns a filtered table. ALL(TableName): Removes all filters from a table. ALLEXCEPT(TableName, Column1, Column2): Removes all filters except specified columns. KEEPFILTERS(FilterExpression): Keeps filters applied while using other functions. 6️⃣ Ranking & Row Context Functions RANKX(Table, Expression, [Value], [Order]): Ranks values in a column.
