# tidyr exercises #### **ACCE Data & Project Management Course** *** ## Example data 1 In an investigation of sexual dimorphism in a tropical bird species, wing length of male and female birds within breeding pairs were recorded across a number of regions within the species range. Reshape the data so that differences in average wing length between sexes could be tested. [`birds.csv`](https://osf.io/k4y3p/) *** ## Example data 2 In an investigation of how different tree species affect tropical rainforest microclimate, measurements of temperature and humidity were made at ground level (below) and above the canopy (above) for individual trees. [`trees.csv`](https://osf.io/7azhs/) *** ## Example data 3 In this study, daily trends in 3 different stocks (X,Y,Z) was monitored daily. We need the data reshaped in an appropriate format that would allow the trend of stocks to be examined as a function of stock identity, month or day. Beware of the date format!
