📊🤔🔍 Hey, friends! Today, we’re talking about overplotting. 📈 Overplotting occurs when there are too many data points in a scatterplot, and the points overlap, making it difficult to see the overall pattern in the data. To address this issue, you can use several techniques, including adding transparency to the points, sampling the data, or […]
Hey, guys! Today, we’re going to talk about covariation. 🤝 So, what is covariation? 🤔 Well, covariation is the tendency for values of two or more variables to change together. 📊 For example, when you practice basketball every day, you’ll likely see an increase in your shooting percentage. That’s covariation! 🏀📈 When variables covary, we […]
Hey, friends! Today, we’re going to talk about charts that are best for exploring relationships in your data. 📈 So, what charts should you use? 🤔 There are a few different charts that can help you explore relationships in your data: scatterplots, bubble charts, line charts, and heatmaps. Let’s dive into each one. 🔍 Scatterplots […]
Hey, guys! Today, we’re talking about the relationship between variables. 📈 When exploring the relationship between variables, it’s important to consider how one variable might be causing the other. This is because it can help you identify possible causal relationships and make more accurate predictions about future outcomes. 🔍 For example, let’s say you’re exploring […]
Hey, friends! Today, we’re talking about multivariate graphs and when it’s best to use them. 📈 Multivariate graphs are data visualizations that show the relationships between three or more variables in a dataset. These graphs can be used to explore complex data sets and identify patterns and relationships that might not be immediately apparent from […]
Hey, friends! Today, we’re talking about ways to explore bivariate data and the characteristics we typically look for when exploring relationships between variables. 📈 Common Ways to Explore Bivariate Data Two common ways to explore bivariate data are correlation coefficients and scatterplots. A correlation coefficient is a statistical measure of the strength and direction of […]
Hey, guys! Today, we’re talking about scatterplots and how to interpret them. 📈 How Do You Interpret the Type of Association Between Variables in a Scatterplot? A scatterplot is a graph that shows the relationship between two variables. The type of association between the variables can be positive, negative, linear, non-linear, strong, or weak. 🔍 […]
Hey, guys! Today, we’re talking about heatmaps and how to read them. 📈 How Do You Read a Heatmap? A heatmap is a graphical representation of data where the values in a matrix are represented as colors. 🔥 The darker the color, the higher the value, and the lighter the color, the lower the value. […]
Hey, guys! Today, we’re discussing frequency contingency tables and how they can help you explore relationships between two variables. 📈 When is it Most Helpful to Use a Frequency Contingency Table? Contingency Table: Favorite Sport by Favorite Music Genre Well, frequency contingency tables are great when you want to explore the distribution of values for […]
What Questions Does Partial Correlation Help Us Answer? Partial correlation is a statistical method used to explore the relationship between two variables while controlling for the effects of one or more other variables. This helps us answer questions such as: Is the relationship between two variables still significant when we control for the effects of […]
