Excel Skill and Concepts a Data Analyst Should Know
Check this 🧵🧵🧵 for more details
Kindly RT 🙏
It is always encouraged that a data analyst should learn how to use Excel or other spreadsheet app to work with data. As a matter of fact, Excel is the closest tool to understanding complex challenges in your Journey.
If you can do it with Excel, you can figure it out for others
Mastering Excel is a Journey and what you end up knowing still depends hugely on your role.
I will however highlight some concepts you should be familiar with as a Data Analyst in Excel.
Note: It is not sufficient to be familiar with them, you should Know WHEN TO USE THEM.

Etwa zehn BTR-82A in einem Dorf in Rostow gestern.
#PutinImKrieg ImageImageImage
Mindestens genau so krass: etwa 40 mobile Radiostationen in Woronesch.
Wie zahlreiche Experten sagen: „Ich weiß nicht, ob Russland einen großen Krieg vorbereitet, aber sollte Russland einen großen Krieg vorbereiten wollen, dann sähe es genauso aus.“

Wer dachte, Putins Truppenaufmarsch sei bereits abgeschlossen … 500 Kilometer östlich von Moskau gefilmte Züge voller Panzer und Raketenwerfer.
Russland bewegt 9 von 10 Einheiten aus dem östlichen Militärbezirk an die Grenze der Ukraine.

On this 21st of December, when the Nifty shed 400+ points in a single day, there was a lot of panic on the news etc.

I heard an analyst say that this could be because of the "December Effect" !

What is this December Effect and why you should know about it ?

1/n
#marketcrash
The December Effect, more commonly known as the "January Effect" is a seasonal decrease in share prices in the month of December and an increase in prices in the month of January !

This is a very popular hypothesis but what's the logic behind it ?

2/n
#january #december
The logic behind this is that in Dec, investors sell there loss making shares to set off taxes against capital gains, causing the market to fall.

Then, in the next year buy those shares back, thus causing a rise in prices in January !

Sounds legit ! 🤔

🌟 A thread of tips, lessons, gotchas, syntactical conventions, semantics, structures and common errors regarding JavaScript.

Follow to be enlightened!

🌟 1: All programming languages works with data, and there are 7 built in data types in #JavaScript:

• null
• undefined
• boolean
• number
• string
• object
• symbol—added in ES6!

They are also called primitive types

#100DaysOfCode
#CodeNewbies
🌟 2: #null essentially means "no data", empty, nada. #undefined means data has not been explicitly defined or declared. #boolean evaluates to either true or false. #numbers are digits between 0-9, #strings are characters enclosed within double quotes

I started playing #guitar in college. Some of my friends back home played, so I thought I'd learn. It's been years since I kept up with it. With no job and an empty house, I had time. Plus, I could crank up my amp. Ava would have hated it. All the more reason to do it.
#vss365
Strumming a few chords or playing a riff through a loud amp usually makes me feel better. It's more of a distraction this time. My amp is a little old. Even a #ragpicker might pass on it. "If you're not going to play it, sell it," Ava nagged. Life always got in the way.
#vss365
Or I got in the way. Not even ten years ago I kept getting sick all the time. Painful stomach cramps would radiate weakness throughout my body. I learned how to wash it away like healing #rainwater. That's when I really started to figure out who I was and what I could do.
