Data Entry & Transformations

💪🏼 Exercise 1

Open the LPD data set in jamovi.

1. Open lpd_2023.sav in jamovi

2. Open LPD_code_tables.pdf where the description of each variable is found

3. Use the codebook to set up the name and values for each variable in our data set.

4. 💬 Practice: How many police stops ended in a search?

💪🏼 Exercise 2

Dummy code the RACE and SEARCH variables

1. Create a new variable using transform that dummy codes the RACE variable (for simplicity: only create two dummy coded variables – white or not and black or not)

2. Create a new variable using transform that dummy codes the SEARCH variable

3. 💬 Chat: Why would you want to dummy code these variables?

💪🏼 Exercise 3

Explore the descriptives

1. Use the Exploration option within the Analyses tab to view the frequencies for your new dummy coded variables.

2. 💬 Chat: What happens if you view the frequencies for the new dummy coded SEARCH variable by RACE?

💪🏼 Exercise 4

Filter the data

1. Imagine you are only interested in looking at cases where the person stopped ended up being lodged in jail based on the OUTCOME variable. Using the Filters function, select only those cases where the person ended up being lodged in jail

2. 💬 Chat: What happens to your existing analyses after applying that filter?
