What are the different types of frequency distribution?

There are several tens of families of distributions. Some of these are:

Uniform discrete

Binomial

Geometric

Hypergeometric

Poisson

Random

Uniform continuous

Gaussian (Normal)

Exponential

Student's t

Fisher F

Chi-squared

Gamma

Weibull

Beta

Log-normal

In addition, there are distributions that are associated with a particular scenario or test statistic.

What is the sample variance with the mean of 190.3?

The mean, by itself, does not provide sufficient information to make any assessment of the sample variance.

What is kick sampling?

Class limits and class boundaries?

The extreme values of a Class (Class - A range of values which incorporate a set of terms.) are called its Class Limits. This means that the Class doesn't contain values beyond the two extremes of its limits.

How do you get an estimate for skirting a trailer?

The panels are typically 16" wide, and 12 feet long. Measure the height of your trailer from the ground to about 6" above the bottom of the frame (for the top piece that holds it in place). You can use this to calculate how many pieces you will need.

For example, if your trailer is 14 x 70', that means you need panels to cover 14 x 2 + 70x2 = 168 feet WIDE, that is, 2016 inches. So, 2016 divided by 16 inches = 126 panels. So, you would need 126 panels that are 16" wide. Then, take into account the length. If you want a really accurate estimate, you should measure the height of your trailer every 16" all the way around your trailer (126 times), and use this to tell how many feet (length) you will need. You will also need 168 feet of the bottom rail which attaches to the ground and holds it in place, also 168 feet of the back top rail and 168 feet of the front top rail (which holds it in place at the top).

You should also allow a little for "waste", i.e., little pieces left over that are too small to be used.

Hope this helps.
