The t-distribution, like the normal distribution, is bell-shaped and symmetric, but it has heavier tails, which means that it tends to produce values that fall far from its mean. T-tests are used in statistics to estimate significance. What Does a T-Distribution Tell You? Tail heaviness is...
When data are normally distributed, plotting them on a graph results a bell-shaped and symmetrical image often called the bell curve. In such a distribution of data,mean, median, and modeare all the same value and coincide with the peak of the curve. However, in social science, a normal ...
Suppose X is normally distributed with mean 20 and standard deviation 4, find the value x_0 such that P(X greater than or equal to x_0) = 0.975. If a random variable X is normally distributed with a mean of 30 and a standard ...
The normal distribution has multiple characteristics, from its symmetry to its bell shape, even the type of variables that it accepts are important characteristics of this distribution. There are two important groups of variables in statistics.
Q. What does a Bimodal Distribution tell you? You’ve got two peaks of data, whichusually indicates you’ve got two different groups.For example, exam scores tend to be normally distributed with a single peak. However, grades sometimes fall into a bimodal distribution with a lot of students...
The experimental group was compared with the control group using the paired sample t test for independent samples when dealing with approximately normally distributed variables and the Wilcoxon rank-sum test when appropriate. One sample t test was used to compare albumin levels of the control group ...
Does ANOVA Rely on Any Assumptions? Yes, ANOVA tests assume that the data is normally distributed and that variance levels in each group are roughly equal. Finally, it assumes that all observations are made independently. If these assumptions are inaccurate, ANOVA may not be useful for comparing...
