Define univariate analysis?

## Answers (1) 2021-03-08
Univariate analysis is referred to be as the easiest way to perform the statistical analysis on the observed data set. The Univariate analysis deals with only one variable. As the name suggests "Uni" which represents "one".
Some information about the Univariate Analysis is as follows:
1) This type of analysis does not deal with finding the relationship as there is only one variable.
2) The main purpose of the univariate analysis is to describe, understands the pattern and summarize the data.
3) The data can be represented in the form of Histogram, Pie charts, Bar Charts etc.
4) The data can be summarized by using measures of dispersion, central tendency etc.
The univariate analysis can be categorized in the two forms, such as the inferential statistics and the descriptive statistics.
Some examples of the univariate analysis are:
a) The analysis of age.
b) The analysis of height.
c) The analysis of monthly income of a family.

Regarding analysis of residuals, decide in each case which assumption for regression inferences may be violated. a. A residual plot-that is, a plot of the residuals against the observed values of the predictor variable-shows curvature. b. A residual plot becomes wider with increasing values of the predictor variable. c. A normal probability plot of the residuals shows extreme curvature. d. A normal probability plot of the residuals shows outliers but is otherwise roughly linear. asked 2020-11-23
Geographical Analysis (Oct. 2006) published a study of a new method for analyzing remote-sensing data from satellite pixels in order to identify urban land cover. The method uses a numerical measure of the distribution of gaps, or the sizes of holes, in the pixel, called lacunarity. Summary statistics for the lacunarity measurements in a sample of 100 grassland pixels are x¯=225 and s=20s=20. It is known that the mean lacunarity measurement for all grassland pixels is 220. The method will be effective in identifying land cover if the standard deviation of the measurements is 10% (or less) of the true mean (i.e., if the standard deviation is less than 22). a. Give the null and alternative hypotheses for a test to determine whether, in fact, the standard deviation of all grassland pixels is less than 22. b. A MINITAB analysis of the data is provided below. Locate and interpret the p-value of the test. Use α=.10α=.10. Test for One Standard Deviation Method Null hypothesisSigma = 22 Method Alternative hypothesisSigma = < 22 The standard method is only for the normal distribution.
