Numpy Overview - What is It Used for Before we start coding with Numpy, let's discuss what it does and how it works. This video will help you understand why Numpy is so important for data analysis. 3m
-
3
Numpy Arrays In this video, we discuss how Numpy arrays work, including how they are much, much faster to work with than regular Python arrays. 4m
-
4
Numpy Operations Let's discuss mathematical operations we can use in Numpy, including scalars. 4m

1
Installing Pandas and Overview - What is It Used for Pandas is a powerful Python data analysis toolkit. In this video, we'll discuss what it does and how it works. 3m
-
2
Pandas Series Pandas series is one of the main "workhorses" of Pandas. We'll discuss how series work and some of the helpful ways you can use them. 5m
-
3
Pandas DataFrames DataFrames are like spreadsheets, and in this video, we start building and using them. 5m
-
4
Selecting Columns and Multiple Columns We discuss how to select individual and multiple columns within a data frame. 3m
-
5
Creating New Columns In this video, we cover how to add a new column to your data frame. 3m
-
6
Removing Columns Let's discuss how to use the drop function to remove a column from your data frame. 3m
-
7
Deleting Rows Deleting a row in a data frame is very similar to deleting a column - but with one small difference. 4m
-
8
Selecting Rows In this video, we'll discuss two different ways to select a row within a data frame, including the loc function. 3m
-
9
Selecting Subsets of Rows and Columns Let's discuss how to select specific points within your data frames, such as the intersection of a row and column, or multiple points within different rows and columns. 4m
-
10
Conditional Selection of DataFrames Selecting data based on conditionals - such as greater than, less than, equal to, not equal to - is an essential part of data analysis. We'll discuss that in this video. 4m
-
11
Multiple Conditions In this video, we'll explain how to select data based on multiple conditional statements. 4m
-
12
Changing Indexes There are times when you may need to reset your index within a data frame, so we'll explain how that works in this video. 4m
-
13
Selecting Specific Cells From Multi-Index Let's discuss multi-indexes: what they are, how they work, and how to select data from them. 6m
-
14
Dealing With Missing Data You may encounter missing data while doing analysis. What should you do? In this video, we'll discuss some helpful alternatives. 6m
-
15
Groupby Grouping Data The groupby function allows us to group different pieces of data together. We'll discuss the function in this video. 3m
-
16
Concatenating, Merging, and Joining Part 1 There are different ways to combine various pieces of data within your data frame. In this video, we'll discuss concatenating. 5m
-
17
Concatenating, Merging, and Joining Part 2 We discuss how to merge and join data frames together in this video. 5m
-
18
Operations: Unique Values and Value Counts In this video, we discuss how to find unique values within a column and how to find value counts as well. 4m
-
19
Operations: Apply Method The apply method allows us to create our own functions and apply them to the data in our columns. 4m
-
20
Operations: Sorting, Ordering, and Finding Nulls In this video, we discuss how to sort and order your data. 3m
-
1
Plotting Histograms In this video, we begin discussing data visualization, and install matplotlib to help us create histograms. 4m
-
2
Plotting Area Plots We discuss how to create another type of data visualization: area plots. 3m
-
3
Plotting Bar Plots In this video, we explain how to create bar plots using your data. 2m
-
4
Plotting Line Plots Let's create line plots and discuss some of the options you can use to change their appearance. 3m
-
5
Plotting Scatter Plots Scatter plots are a bit more complicated, but can be helpful ways to visualize your data. 4m
