When I’m stressed or under pressure, I focus on staying calm and organized. I take a step back, break the problem into smaller parts, and tackle one thing at a time. I also prioritize tasks, avoid overthinking, and keep communication clear—especially if a deadline is involved. Taking short breaks or writing things down also helps me reset and stay focused.
One tough situation I faced was when a co-worker strongly disagreed with my approach on a shared task and became uncooperative. Instead of reacting emotionally, I invited them for a private conversation. I listened to their concerns first, then shared my side respectfully. We found common ground by agreeing on a mix of both our ideas. In the end, the project went smoothly, and we worked better as a team. That experience taught me how far patience and open communication can go in resolving workplace tension.
Incomplete or missing data is a common challenge in data analysis. Whether it’s skipped survey responses, blank spreadsheet cells, or unavailable values, missing data can affect the accuracy and reliability of your results.
The key is to handle missing data thoughtfully so you can still draw valid conclusions without misleading your interpretation.

🔍 Common Ways to Handle Missing Data:
1. Identify the Missing Data
Start by locating where and how much data is missing.
Check: Is it random or following a pattern? Are entire sections missing or just a few values?
2. Remove Incomplete Entries (if appropriate)
If only a small number of rows are missing data, and they don’t heavily impact the dataset, you can safely remove them.
3. Use Imputation (Estimate Missing Values)
If the dataset is large and important, you can fill in missing values using methods like:
– Mean or median substitution (for numerical data)
– Mode (for categorical data)
– Regression or predictive models (for more advanced cases)
4. Use Available Data Only
In some cases, you can perform analysis using just the complete parts of the dataset — as long as it doesn’t bias your results.
5. Flag and Acknowledge Missing Data
Be transparent in reports. Clearly mention how much data is missing and how it was handled.
6. Ask Why the Data Is Missing
Sometimes missing data reveals a deeper issue (e.g., system errors, survey confusion). Understanding the cause can help prevent future problems.
Imagine you’re analyzing survey responses from 1,000 people, but 100 skipped the income question.
-
Option 1: Exclude those 100 responses if income is critical to your analysis.
-
Option 2: If income correlates with other known answers (like job title), estimate it using average values for each group.
We are given:
-
When the greatest number divides 3026, it leaves remainder 11
-
When it divides 5053, it leaves remainder 13
Let the required greatest number be x.
🟢 Step 1: Subtract the remainders
If x divides (3026 − 11) and (5053 − 13), then:
-
3026 − 11 = 3015
-
5053 − 13 = 5040
So, x must be a number that divides both 3015 and 5040 exactly.
🟠 Step 2: Find HCF of 3015 and 5040
Let’s use the Euclidean Algorithm:
-
5040 ÷ 3015 = 1 remainder 2025
-
3015 ÷ 2025 = 1 remainder 990
-
2025 ÷ 990 = 2 remainder 45
-
990 ÷ 45 = 22 remainder 0
✅ So, HCF(3015, 5040) = 45
✔ Final Answer:
The greatest number that will divide 3026 and 5053 leaving remainders 11 and 13 respectively is:
👉 45
