The Mean Absolute Deviation (MAD) is a way to measure how spread out the values are in a set of data. It tells us on average how far each data value is from the average of all the data values. To find the MAD, we take the absolute value (ignoring negative or positive signs) of […]
📊📈🔍 Hey guys, let’s talk about variance and standard deviation! 📊📈🔍 The variance measures how far data values lie from the mean of a distribution. It tells us how spread out the values are from the average. It’s like the difference between a group of people standing close together versus spread out across a wide […]
📊📈🔍 Hey guys, let’s talk about the interquartile range! 📊📈🔍 The Interquartile Range (IQR) is a measure of variability in a distribution. It’s the range between the first quartile (25th percentile) and the third quartile (75th percentile) of the data. The interquartile range is a great way to describe the variability of points near the […]
📊📈🔍 Hey, everyone. Welcome to today’s tutorial on understanding the range of a distribution! 📊📈🔍 The range of a distribution is simply the difference between the highest and lowest values in the distribution. It’s like the range of a basketball player’s shots – the difference between their longest and shortest shots. The range tells us […]
📊📈🔍 Hey guys, let’s talk about charts that are best for exploring dispersion in a distribution! 📊📈🔍 Histograms and box plots are two of the best charts for exploring dispersion in a distribution. Histograms show the frequency of values in a distribution, while box plots show the range and distribution of the values. Histograms are […]
📊📈🔍 Hey guys, let’s talk about measures of variation in distributions! 📊📈🔍 Measures of variation tell us how spread out the values are around the central value. If the values are tightly clustered around the center, then there is low variation. But if the values are spread out over a wider range, then there is […]
📈🔍📊 Hey guys, let’s talk about distributions and dispersion! 📊🔍📈 How Does a Distribution with Low Dispersion Compare to One with High Dispersion? Imagine you’re trying to hit a target with darts. If you’re really good, your darts will all be clustered tightly around the bullseye. This is kind of like a distribution with low […]
📈🔍📊 Hey, everyone. Let’s talk about distributions and why they can vary! 📊🔍📈 Why Is There Variation in a Distribution? Think of it like baking cookies. Even if you follow the same recipe every time, your cookies might come out a little bit different each time you make them. This is because there are many […]
Hey, friends! Today, we’re talking about scatterplots and how they can be used to explore data. 📈 So, what does a scatterplot display? A scatterplot displays data point pairs and the relationship between two variables. It shows how one variable changes in relation to the other variable. 🔍 For example, let’s say you’re looking at […]
Hey, friends! Today, we’re talking about line charts and how they can be used to explore associations between variables. 📈 So, what are the benefits of using a line chart to explore the association between variables? 🤔 Line charts are easy to interpret and are good for exploring continuous variables with few discrete points. They show […]
