     • The normal distribution has a symmetrical shape. It is sometimes called a bell curve because a plot of the distribution looks like a bell sitting on the ground.

   What is a box plot for a normal distribution?

   • A box plot for a normal distribution shows that the mean is the same as the median. It also shows that the data has no extreme values. The data will be symmetrical. Take a look at the two box plots in Figures 8 and 9 below. The data in Figure 8 is from a nearly normal distribution. The data in Figure 9 is from a non-normal distribution.

   What is a normal distribution?

   • Data values that are a sample from a normal distribution are said to be “normally distributed.” Instead of diving into complex math, let’s look at the useful properties of the normal distribution and why it is important in analyses. First, why do we care about the normal distribution? Many measurements are normally distributed, or nearly so.

   What is a normal quantile plot?

   • A normal quantile plot shows a normal distribution as a straight line instead of as a bell curve. If your data are normal, then the data values will fall close to the straight line. If your data are non-normal, then the data values will fall away from the straight line.

   How many parameters does a normal distribution have?

   • All distributions have parameters, and some have more than two. In any situation, the parameters will define a specific distribution. Let's look at some examples of normal distribution curves. Figure 2 shows two normal distributions, each with the same mean of 30. The thinner, taller distribution shown in blue has a standard deviation of 5.

   4 days ago · The histogram shows that the center of the data is somewhere around 45 and the spread of the data is from about 30 to 65. It also shows the shape of the data as roughly mound-shaped. This shape is a visual clue that the data is likely to be from a normal distribution.

   2 days ago · In probability theory and statistics, the chi-squared distribution (also chi-square or -distribution) with degrees of freedom is the distribution of a sum of the squares of independent standard normal random variables. The chi-squared distribution is a special case of the gamma distribution and the univariate Wishart distribution.

   1 day ago · In probability theory, the central limit theorem ( CLT) states that, under appropriate conditions, the distribution of a normalized version of the sample mean converges to a standard normal distribution. This holds even if the original variables themselves are not normally distributed.
