Which statement best describes the distinction between a parameter and statistic?
Answer: C Step-by-step explanation: A parameter is used to estimate a statistic Before you start, you may want to read these overviews: A statistic and a
parameter are very similar. They are both descriptions of groups, like “50% of dog owners prefer X Brand dog food.” The difference between a statistic and a parameter is that statistics describe a sample. A parameter describes an entire population. Watch the video or read the steps

How to tell the difference between a statistic vs parameter For example, you randomly poll voters in an election. You find that 55% of the population plans to vote for candidate A. That is a statistic. Why? You only asked a sample—a small percentage— of the population who they are voting for. You calculated what the population was likely to do based on the sample. Censuses result in a parameter about the population.You could ask a class of third graders who likes vanilla ice cream. 90% raise their hands. You have a parameter: 90% of that class likes vanilla ice cream. You know this because you asked everyone in the class. Steps to tell the difference between a statistic and a parameter:Step 1: Ask yourself, is this a fact about the whole population? Sometimes that’s easy to figure out. For example, with small populations, you usually have a parameter because the groups are small enough to measure: Examples of parameters:
Step 2: Ask yourself, is this obviously a fact about a very large population? If it is, you have a statistic. Examples of statistics:
If in doubt, think about the time and cost involved in surveying an entire population. If you can’t imagine anyone wanting to spend the time or the money to survey a large number (or impossible number) in a certain group, then you almost certainly are looking at a statistic.

What is the difference between parameter and statistic example?Parameters are numbers that describe the properties of entire populations. Statistics are numbers that describe the properties of samples. For example, the average income for the United States is a population parameter. Conversely, the average income for a sample drawn from the U.S. is a sample statistic.
What described by a parameter and which is described by a statistic is the difference between a population and a sample which is?A parameter is a measure that describes the whole population. A statistic is a measure that describes the sample. You can use estimation or hypothesis testing to estimate how likely it is that a sample statistic differs from the population parameter.
