This project is an assignment of the Udacity Nanodegree Data Analyst.
##Project Overview In a Stroop task, participants are presented with a list of words, with each word displayed in a color of ink. The participant’s task is to say out loud the color of the ink in which the word is printed. The task has two conditions: a congruent words condition, and an incongruent words condition. In the congruent words condition, the words being displayed are color words whose names match the colors in which they are printed: for example RED, BLUE. In the incongruent words condition, the words displayed are color words whose names do not match the colors in which they are printed: for example PURPLE, ORANGE. In each case, we measure the time it takes to name the ink colors in equally-sized lists. Each participant will go through and record a time from each condition.
Following questions are answered in this project:
- What is the independent variable?
- What is the dependent variable?
- What is an appropriate set of hypotheses for this task?
- What kind of statistical test shall be performed?
Those sections are included in the project:
- Reporting of descriptive statistics with measures of central tendency and measures of variability.
- Visualizations that show the distribution of the sample data.
- A paired t-test is conducted.
##Run You can run the .ipynb file with the python notebook. Those libraries are used:
- pandas
##Data The data used is provided in this project with the stroopdata.csv.
