Test statistics that follow a chi-squared distribution arise from an assumption of independent normally distributed data, which is valid in many cases due to the central limit theorem. A chi-squared test can be used to attempt rejection of the null hypothesis that the data are independent.
Voles, also known as mice, live in field, forest, and shrub habitats. Voles can cause extensive damage when they move into our turf and landscaped gardens in search of food and shelter. Voles do not hibernate and are active throughout the year. They can reproduce year round having many litters per year.
Vole Habitat. Vole habitat can be a wide variety of climates and flora. The meadow vole has a preference for areas with heavy cover. Heavily grassed areas such as meadows or edge habitat make excellent vole habitat as well.Some voles are quite happy to live in orchards and cultivated fields.ole Habitat-Range. Home ranges will vary between species but are normally quite small. The meadow vole will normally stay within 400 feet of their home. In the winter time their activity will not lead them much further than their underground vole habitat.
