Answer 1

A statistic is a numerical summary of a sample, while a parameter is a summary of a population. Organizing data effectively requires choosing the appropriate method depending on the range and volume of data. Descriptive statistics provide summarization, with the mean, median, and mode as common measures.

Step-by-step explanation:

When we talk about a statistic, we refer to a numerical summary of a sample. This differs from a parameter, which is a numerical summary of a population.

For instance, in a study determining average spending at a grocery store's produce department, the average from a sample of 1,000 visits is a statistic, whereas the average of all visits by all customers would be the population parameter.

To study the distribution of data, an organized approach is necessary. For a data set with a small range and little data, a simple frequency distribution is appropriate. When the data set has a small range but contains a lot of data, techniques like rank order or a simple frequency distribution could be effective.

If the data set contains a large range with many data points, a grouped frequency distribution is usually best since it helps summarize the data effectively.

Regarding the strength of grip across ages, if the distribution of data is expected to have a bell-shaped curve, it is referred to as a normal distribution. If the curve trails off to the left, it's skewed negatively, and if it trails off to the right, it's skewed positively. Symmetrical distributions have equal spread on both sides of the center.

Descriptive statistics are utilized to summarize data, such as through the calculation of measures like mean, median, mode, range, and standard deviation. For example, the mean provides an average of the data, the median delivers the middle value when data is ordered and the mode indicates the most frequently occurring value.
