Encountered a data discrepancy while analyzing sales data
Discovered inconsistencies in sales figures between different data sources
Investigated the issue by cross-referencing data and identifying the source of the discrepancy
Resolved the problem by updating the incorrect data and ensuring consistency across all sources
A p value is a measure of the strength of evidence against the null hypothesis in a statistical hypothesis test.
P value is a probability value that measures the likelihood of obtaining results at least as extreme as the observed results, assuming the null hypothesis is true.
A p value less than 0.05 is typically considered statistically significant, indicating strong evidence against the null hypothesis.
A p value greate...
Basic regression is a statistical method used to analyze the relationship between a dependent variable and one or more independent variables.
Regression helps in predicting the value of the dependent variable based on the values of independent variables.
It is used to understand the strength and direction of the relationship between variables.
Common types of regression include linear regression, logistic regression, and

Describe a problem you encountered working with your data and how you resolved it
A p value is a measure of the strength of evidence against the null hypothesis in a statistical hypothesis test.
P value is a probability value that measures the likelihood of obtaining the observed data if the null hypothesis is true.
A p value less than 0.05 is typically considered statistically significant, indicating strong evidence against the null hypothesis.
A p value greater than 0.05 suggests that the observed da...
Basic regression is a statistical method used to analyze the relationship between a dependent variable and one or more independent variables.
Regression analysis is used to predict the value of the dependent variable based on the values of the independent variables.
The most common type of regression is linear regression, where a straight line is used to model the relationship between variables.
Other types of regression ...

The Convex Hull is the smallest convex polygon that encloses all given points.
Sort the points based on their x-coordinate.
Find the upper hull by starting from the leftmost point and moving clockwise.
Find the lower hull by starting from the rightmost point and moving counterclockwise.
Combine the upper and lower hulls to form the convex hull.
The strategy is to always subtract the number chosen by the friend from 4 to ensure reaching 16 first.
Start with 20 and subtract the number chosen by the friend from 4.
Continue this strategy until reaching 16 before the friend reaches 17-19.
Ensure the friend ends up at any number between 17 to 19 before reaching 16.
The problem involves finding an element in a matrix that is sorted both row-wise and column-wise.
Start from the top-right corner of the matrix
Compare the target element with the current element
If the target is smaller, move left; if larger, move down
Repeat until the target is found or the matrix boundaries are crossed

Expected number of tosses of a fair coin to get 3 consecutive heads.
The probability of getting 3 consecutive heads is 1/8
The expected number of tosses to get 3 consecutive heads is 14
This can be calculated using the formula E(X) = 2^k + 2^(k-1) + 2^(k-2) + ... + 2^2 + 2^1 + 2^0, where k is the number of consecutive heads required
Go second. The probability of winning is higher when going second.
The probability of winning when going first is (1/n+1), while the probability of winning when going second is (n/n+1)
This is because the first player has a chance of drawing the black ball on their turn, while the second player has a chance of drawing the black ball on their turn or the first player's turn
For example, if there are 10 red balls and 1 blac...
What is the most likely value of the last roll in a game where a die is rolled until the sum of all rolls is at least 100?
The last roll must be at least 4 to reach a sum of 100
The probability of rolling a 4, 5, or 6 is 1/2
The most likely value of the last roll is 4 or 5
Algorithm to search for a number in an n x n matrix with sorted rows and columns.
Start from the top-right corner of the matrix
If the current element is greater than the target, move left
If the current element is less than the target, move down
Repeat until the target is found or the bottom-left corner is reached
Algorithm to find largest common subarray of two arrays of size n
Create a 2D array to store the lengths of common subarrays
Traverse both arrays and fill the 2D array with lengths of common subarrays
Find the maximum length and its corresponding ending index in the 2D array
Use the ending index to retrieve the largest common subarray from either of the arrays

Probability of a randomly dropped rod of length L intersecting a line on a 2D plane with infinite parallel, vertical lines.
The probability depends on the length of the rod L.
The probability can be calculated using geometric probability.
The probability is 1 - (2L - 1) / infinity.
For example, if L = 1, the probability is 0.5.
If L = 2, the probability is 0.75.
