Data Analysis Books | Python | SQL | Excel | Artificial Intelligence | Power BI | Tableau | AI Resources (@learndataanalysis) Ingliz til segmentidagi kanali faol ishtirokchi. Hozirda hamjamiyat 51 904 obunachidan iborat bo'lib, Taʼlim toifasida 3 349-o'rinni va Hindiston mintaqasida 7 018-o'rinni egallagan.
📊 Auditoriya ko‘rsatkichlari va dinamika
невідомо sanasidan buyon loyiha tez o‘sib, 51 904 obunachiga ega bo‘ldi.
23 Iyun, 2026 dagi oxirgi ma’lumotlarga ko‘ra kanal barqaror faollikka ega. Oxirgi 30 kunda obunachilar soni 428 ga, so‘nggi 24 soatda esa 17 ga o‘zgardi va umumiy qamrov yuqori darajada qolmoqda.
- Tasdiqlash holati: Tasdiqlanmagan
- Jalb etish (ER): Auditoriya o‘rtacha 4.72% darajada jalb etiladi. Nashrdan keyingi dastlabki 24 soatda kontent odatda umumiy obunachilar sonining N/A% ini tashkil etuvchi reaksiyalarni to‘playdi.
- Post qamrovi: Har bir post o‘rtacha 2 447 marta ko‘riladi; birinchi sutkada odatda 0 ta ko‘rish yig‘iladi.
- Reaksiyalar va o‘zaro ta’sir: Auditoriya faol: har bir postga o‘rtacha 4 ta reaksiya keladi.
- Tematik yo‘nalishlar: Kontent analyst, |--, excel, visualization, analytic kabi asosiy mavzularga jamlangan.

Yuqori yangilanish chastotasi (oxirgi ma’lumot 24 Iyun, 2026 da olingan) sababli kanal doimo dolzarb va katta qamrovli bo‘lib qoladi. Analitika auditoriya kontent bilan faol hamkorlik qilishini, uni Taʼlim toifasidagi muhim ta’sir nuqtasiga aylantirishini ko‘rsatadi.
SELECT *
FROM (
SELECT name, department, salary,
ROW_NUMBER() OVER (PARTITION BY department ORDER BY salary DESC) AS rn
FROM employees
) AS ranked
WHERE rn <= 2;
✔ Why it works:
– PARTITION BY department resets row numbers (starting at 1) for each dept group, treating them as mini-tables.
– ORDER BY salary DESC ranks highest first within each partition.
– WHERE rn <= 2 grabs the top 2 per group—subquery avoids duplicates in complex joins!
💡 Pro Tip: Swap to RANK() if ties get equal ranks (e.g., two at #1 means next is #3, but you might get 3 rows); DENSE_RANK() avoids gaps. For big datasets, this scales well in SQL Server or Postgres.

✍️ AI Use: Input data is often stored as vectors/matrices. Model weights and activations are matrix operations.
2️⃣ Statistics & Probability
Helps AI models make predictions, handle uncertainty, and measure confidence.
✅ Key Concepts: Mean, Median, Standard Deviation, Probability
import statistics data = [2, 4, 4, 4, 5, 5, 7] mean = statistics.mean(data) # Output: 4.43✍️ AI Use: Probabilities in Naive Bayes, confidence scores, randomness in training. 3️⃣ Calculus (Basics) Needed for optimization — especially in training deep learning models. ✅ Key Concepts: Derivatives, Gradients ✍️ AI Use: Used in backpropagation (to update model weights during training). 4️⃣ Logarithms & Exponentials Used in functions like Softmax, Sigmoid, and in loss functions like Cross-Entropy.
import math
x = 2
print(math.exp(x)) # e^2 ≈ 7.39
print(math.log(10)) # log base e
✍️ AI Use: Activation functions, probabilities, loss calculations.
5️⃣ Vectors & Distances
Used to measure similarity or difference between items (images, texts, etc.).
✅ Example: Euclidean distance
from scipy.spatial import distance
a = [1, 2]
b = [4, 6]
print(distance.euclidean(a, b)) # Output: 5.0
✍️ AI Use: Used in clustering, k-NN, embeddings comparison.
You don’t need to be a math genius — just understand how the core concepts power what AI does under the hood.

6️⃣ Build Strong Programming Skills
Python (Pandas, NumPy, Scikit-learn) and R are essential for data manipulation and analysis.
7️⃣ Understand Machine Learning Basics
Know key algorithms—linear regression, decision trees, random forests, and clustering—to develop predictive models.
8️⃣ Learn Dashboarding & Storytelling
Power BI and Tableau help convert raw data into actionable insights for stakeholders.
