In this short post, I will show you a quick fix for the error “unsupported operand type(s) for +: ‘float’ and ‘NoneType’” with Pyvttbl. In earlier posts, I have shown how to carry out ANOVA using Pyvttbl (among other packages. See posts 1, 2, 3, and 4 for ANOVA using pyvttbl). However, Pyvttbl is not

In this post, PyCharm vs Spyder will be compared. If you have followed my blog you may have noticed that a lot of focus has been put on how to learn programming (particularly in Python). I have also written about Integrated Development Environments (IDEs). I think that an IDE may, in fact, be very useful

In this post, you are going to learn how to create a simple experiment using the free experiment building software OpenSesame. As I have previously written about, OpenSesame is an application based on Python for creating Psychology, Neuroscience, and Economics experiments. It offers a nice and easy-to-use interface. In this interface, you can drag and

In this short post, we are going to revisit the topic of how to carry out descriptive statistics in Python. In the previous post, I used Pandas (but also SciPy and Numpy, see Descriptive Statistics Using Python) but now we will only use Numpy. The descriptive statistics we will calculate are the central tendency (in

In this video you learn how to create a Flanker task using the Python package Expyriment. If you don’t know Expyriment it is an open-source library. You can program your experiments and run on Linux, Windows, and OS-x computers and Android devices. In the tutorial you will get familiar with Expyriment and get to create

Inspired by my post for the JEPS Bulletin (Python programming in Psychology), where I try to show how Python can be used from collecting to analyzing and visualizing data, I have started to learn more data exploring techniques for Psychology experiments (e.g., response time and accuracy). Here are some methods, using Python, for visualization of

Python is gaining popularity in many fields of science. This means that there also are many applications and libraries specifically for use in Psychological research. For instance, there are Python packages for collecting data, doing basic statistics, and analyzing brain imaging data. In this post, I have collected some useful Python packages for researchers within
