In this slideshare I’m going to show you all the different types of survey you will come across as a data analyst – and the one thing you need to know! You can get these tips in my video course *How to Analyse Categorical Survey Data in Excel and in R* here: http://bit.ly/HACSDERSS Here’s a quick rundown of what you’re going to learn: Step 1: you’ll learn about the different types of survey that all analysts need to know. Step 2: you’ll learn why they’re different and when to use each one. Step 3: you’ll learn why they’re all the same to a data analyst! In the end, you’ll have a strong understanding of the different types of surveys so you can plan every aspect of your next study to make it completely disaster-proof. #survey #surveyanalysis #statistics ---------------------------------------------------------------------------------------------- Follow me on YouTube for more stats and machine learning hints & tips ---------------------------------------------------------------------------------------------- ▸ https://www.youtube.com/channel/UC8pp1dYKKjQrJ8MOW2_53DA ------------------------ Related Resources ------------------------ Probability Theory – 5 Awesome Things You Didn't Know (FREE): ▸ https://www.chi2innovations.com/5-awesome-things-you-didnt-know-about-probability-theory-video/ Probability Theory Quiz – Test Your Knowledge (FREE): ▸ https://www.chi2innovations.com/probability-theory-quiz-test-your-knowledge/ Statistics – The Big Picture (Video Course - Start FREE) ▸ http://bit.ly/HACSDERSS ------------------------------------------------- Find me on TwitFace (and elsewhere) ------------------------------------------------- Facebook: https://www.facebook.com/chi2innovations/ Twitter: https://twitter.com/eelrekab LinkedIn: http://www.linkedin.com/in/eelrekab Pinterest: https://www.pinterest.co.uk/baker7435 Blog: https://www.chi2innovations.com/blog/ The Hive: https://www.chi2innovations.com/the-hive/ Google+: (may it rest in peace!)

- Survey A survey is a research method used for collecting data to gain information and insights on a particular topic of interest
- 2Types of Survey Survey Cross-Sectional Longitudinal
- Cross-Sectional Survey Used to study a topic of interest at a specific point in time › We use these studies to get a quick & cheap summary
- Cross-Sectional Survey – Example Do you have lung cancer? › Yes › No
- Yes No Men 10 50 Women 15 25 0 10 20 30 40 50 60 % Descriptive stats
- Longitudinal Survey Used to study a topic of interest over a period of time › We use these studies to examine cause and effect
- Cause Effect For how long have you smoked? › Non-smoker › Less than 10 years › More than 10 years Do you have lung cancer? › Yes › No
- 0 5 10 15 20 25 30 35 Never Smoked < 10Years > 10Years Lung Cancer Linear (Lung Cancer) A trend!
- 2Types of Longitudinal Survey Longitudinal Case Control Cohort
- Case Control Survey Outcome Present Outcome Not Present Compare Case Control Outcome: • Disease • Sale •Opinion
- Outcome Present Cause Present Cause Not Present Outcome Not Present Cause Present Cause Not Present Compare Time
- Cohort Survey Cause Present Cause Not Present Compare Case Control Cause: • Smoking • Product placement •Advert
- Cause Present Outcome Present Outcome Not Present Cause Not Present Outcome Present Outcome Not Present Compare Time
- 2Types of Cohort Survey Cohort Retrospective Prospective
- Retrospective Survey Check back into existing records to investigate cause & effect › Looking backwards into the past
- Prospective Survey Investigate cause and effect over time › Looking forwards into the future
- DifferentTypes of Survey Survey Cross-Sectional (summary) Longitudinal (cause & effect) Case Control (cause) Cohort (effect) Retrospective (past) Prospective (future)
- Most Importantly !!! Whatever type of survey you’re conducting › The way you analyse them all is EXACTLY the same Same types of data Same descriptive statistics Same data analysis techniques Same statistical tests
