Statistics
Statistics deals with collecting, organizing, and interpreting numerical data. An important aspect of statistics is the analysis of population characteristics inferred from sampling.

An unkown number is greater than 456782 but less than 489211 the thousands digits is greater than 4 the ten thousands digit is not 6 or 7 give a range of numbers that the unknown number could be?
Do you take the outlier out when calculating mean and median?
No. The mean is calculated by adding all of the numbers, then dividing that sum by [how many numbers]. The trimmed meandoes remove some outliers (same number of outliers at top and bottom, though). The median is the middle number of a sorted set.
How many people visit fl per year?
Florida attracts approximately 100 million visitors each year, making it one of the most popular tourist destinations in the United States. This influx is driven by its warm climate, beautiful beaches, and attractions like Walt Disney World and Universal Studios. The tourism industry plays a significant role in the state's economy, supporting countless jobs and businesses.
This is a very simple explanation that I have given to my Grade 6 students. Bernoulli's Theory, which originally was applied to his research in fluids & medicine (particularly blood pressure), helps explain how planes fly. He discovered the principal that the pressure of a fluid decreases when its speed or velocity increase, this prinicpal was also later discovered to apply to air pressure as well. This helps us to understand that when a plane is speeding up for take off, the faster it goes the less air pressure is exerted on it and therefore the plane is able to 'lift-off' the ground and fly. A plane that does not obtain sufficient speed on the ground, for its size & weight, may not be able to take off successfully.
Yes; it will form a honey-comb shape.

How to figure the percentile 199 out of 538?
199 divided by 538 =0.3698 x 100 = 36.98% OR 199 x 100 = 19900 divided by 538 = 36.98%
Perditum sum means "I am ruined" in Latin, but only if the speaker is of the neuter gender. A man would say perditus sum; a woman, perdita sum.
How do you do the median of a number?
1. Put the set of numbers in order.
2. look for the middle number overall.
3. You just did it.
********************************
1.Put all the numbers in order from least to greatest
2. Cross off the first number in the set.
3. Cross off the last number in the set.
4. Continue with this process until there is only one number left. That is the median.
Is cluster sampling is a type of stratified random sampling?
No. Cluster sampling and stratifed random sampling are different, though often confused. (They may, however, be used in conjunction in some sampling designs.) Both are types of random sampling.
STRATIFIED sampling involves identifying a variable that will break up your population into separate homogeneous groups (homogeneous in terms of the variable you are interested in). For example, suppose you want to know about the attitudes of kids about their future. Perhaps you have reason to believe this will change with time. If you collected a sample from high schools, you could stratify by grade, giving you 4 relatively homogeneous groups: freshmen, sophomores, juniors, seniors. Then, a common approach is to sample a similar number from each group.
Sometimes, though, separating the groups isn't so clear cut. Perhaps you want to stratify based on religion. You can't tell this from looking at a person. So perhaps you collect sample data and apply strata after the fact! This can be useful, but there are some statistical techniques that require equal (or nearly) sample sizes for the strata.
CLUSTER sampling involves breaking your population into fairly similarly sized groups called clusters (try googling MSE for an example). But now you want each cluster to contain a heterogeneous mix of individuals. Then, you take a random selection of these clusters and completely enumerate inside of those selected clusters. The problem with cluster sampling is that the cluster has now become your sample unit, instead of individuals which is what you probably hoped. This can be used for counting species, or just for contacting certain populations like apartment dwellers, nursing home residents, etc. The clusters could be apartment buildings in a city. So instead of taking a random sample of apartment dwellers, you would actually randomly select a few of the buildings and talk to everyone inside! Often, this is much more cost efficient. :)

How many ways can you arrange the digits 985 with four dif numbers?
985,958,895,859,589,598. It should be 6.
Hope I helped.
Possible you want 4 digit numbers using the digits 9 8 and 5 and you want to know how many of those there are?
