Do this by applying a filter to extract the first births, then use mutate() to create a new column called birth_order that labels these rows as 'first'. Split the dataset into two parts, a first_births dataset and an other_births dataset. There are a couple of different ways that you can create the birth_order column (you should pick one or the other): We will do this by creating a new column called birth_order. Next, we need to label all births in live_births as either 'first' or 'other' so that we can easily find the children that are first borns and the ones that are not. Filter the dataset so that it only contains outcomes with live births and assign this result to a new variable live_births.

Refer back to our earlier inference assignment (Assignment 6 on the yawning Mythbusters) if you don't remember how to write particular pieces of code.Īddressing the question 'do first born children either arrive early or late when compared with non-first-borns?' means that we should only consider live births in the dataset. For outcomes other than live birth, this field is blank

Serial number for live births the code for a respondent's first child is 1, and so on. Integer code for the outcome of the pregnancy, with a 1 indicating a live birth Integer duration of the pregnancy in weeks Complete descriptions of all the variables can be found in the NSFG Cycle 6: Female Pregnancy File Codebook. We only require a few variables to answer the above question, which are listed below. The dataset contains 244 variables collected from 13,593 women. The questions in this assignment will guide you through the process of answering this question using statistical inference. Your analysis will revolve around answering the following question,ĭo first born children either arrive early or late when compared with non-first-borns?
