### Member Training: An Introduction into the Grammar of Graphics

June 1st, 2021 by

As it has been said a picture is worth a thousand words and so it is with graphics too. A well constructed graph can summarize information collected from tens to hundreds or even thousands of data points. But not every graph has the same power to convey complex information clearly. (more…)

### Eight Data Analysis Skills Every Analyst Needs

October 24th, 2019 by

It’s easy to think that if you just knew statistics better, data analysis wouldn’t be so hard.

It’s true that more statistical knowledge is always helpful. But I’ve found that statistical knowledge is only part of the story.

Another key part is developing data analysis skills. These skills apply to all analyses. It doesn’t matter which statistical method or software you’re using. So even if you never need any statistical analysis harder than a t-test, developing these skills will make your job easier.

### Creating Graphs in Stata: From Percentiles to Observe Trends (Part 2)

September 23rd, 2016 by

In a previous post we discussed the difficulties of spotting meaningful information when we work with a large panel data set.

Observing the data collapsed into groups, such as quartiles or deciles, is one approach to tackling this challenging task.  We showed how this can be easily done in Stata using just 10 lines of code.

As promised, we will now show you how to graph the collapsed data. (more…)

### Member Training: Communicating Statistical Results: When to Use Tables vs Graphs to Tell the Data’s Story

May 1st, 2016 by

In this webinar, we’ll discuss when tables and graphs are (and are not) appropriate and how people engage with each of these media.

Then we’ll discuss design principles for  good tables and graphs and review examples that meet these principles. Finally, we’ll show that the choice between tables and graphs is not always dichotomous: tables can be incorporated into graphs and vice versa.

Participants will learn how to bring more thoughtfulness to the process of deciding when to use tables and when to use graphs in their work. They will also learn about design principles and examples they can adopt to create better tables and graphs.

Note: This training is an exclusive benefit to members of the Statistically Speaking Membership Program and part of the Stat’s Amore Trainings Series. Each Stat’s Amore Training is approximately 90 minutes long.

### R Graphics: Multiple Graphs and par(mfrow=(A,B))

December 16th, 2014 by

Today we see how to set up multiple graphs on the same page. We use the syntax ` par(mfrow=(A,B))` (more…)

### Argggh! How Do I Output Tables and Graphs From Stata?

October 24th, 2014 by

For my first assignment using Stata, I spent four or five hours trying to present my output in a “professional” form. The most creative method I heard about in class the next day was to copy the contents into Excel, create page breaks, and then copy into Word.

SPSS makes it so easy to copy tables and graphs into another document. Why can’t Stata be easy?

Anyone who has used Stata has gone through this and many of you still are. No worries, help is on the way! (more…)
