7.5First, put the numbers in order from least to greatest. Then pick the number that is in the middle of the newly ordered set. The middle number of the newly ordered set is 7.

Statistical because there can be multiply possible awnsers therefor you can find the mean mode median and range. You can find these because there can be multiple different answers so multiple sets of data. So it is statistical.

1. The medication is the independent variable, and the hair growth is the dependent variable. The independent variable does not depend on anything else in the experiment. Thus, whether the patient does or does not take the medication is the independent variable. It has 2 possible values: yes or no. The amount of hair growth is the dependent variable, since (theoretically) it depends on whether the patient takes the medication.

Mean = 6, mode =8Mean is found by adding all the numbers together and dividing by the number of digits in the set. 4+9+8+2+16+4+4+8+9+6 =70/10 = 7 = mean Mode is the number that is repeated the most = 4

The correct answer is option A Age is classified as nominal data. Nominal data is a type of data that is commonly used to name variables. They can have numbers assigned to them just like ages, the pinned number on a sport person. Nominal data are categorical and they belong to a specified category. Ordinal data tells the position of something in a list, you cannot do arithmetic with ordinal numbers, and they are only used to show sequences. Example of such is: first, second, third, and fourth. Interval data is used to measure in scales; it is used to measure things between two extremes. Eg On the scale of 1 to 10, what is the threshold of your pain? Ratio data is used to compare many variables. Eg Mary can be as twice as tall as Jane.

Statistical questionThis is a statistical question because students could provide a range of responses, such as 0 hours, 1 hour, or 5 hours.

I stand to be corrected, but I think all choices are wrong. A nominal scale variable is a qualitative or categorical type of variable and only used for identification purposes, hence it is not quantifiable. Therefore choices 1, 2, 3 are all wrong. Choice 4 is also wrong because being a qualitative type variable, it can be classified into many categories.

As researchers gather information, they may have to conduct a study. In this study, they have to gather a sample of something in order to analyze the information from that sample. For example, it could be that a survey needs to be conducted by a group of people and these people need to answer some questions about the study’s topic. However, if the researcher’s study involved a population of teenagers, the researcher could not ask every teenager. Instead, the researcher would have to ask a sample of the population. So, if the researcher uses a sample, the probability that it is random would be great. Then this method would limit conscious and unconscious sampling bias. It would also be accurate and represent the population.

Non-statistical questionThis is not a statistical question because there will be one response rather than a variety of responses.

The correct answer depends on what form you want to give the answer in. If you want to give the total number of hits or misses, the correct answer would be “B”, any whole number between 0 and 8. This is an empirical data point, and simply gives the total she made or missed. If you want to give a percentage, or a decimal point out of 100, the answer “A” would be better: any number between 0 and 1. This is also empirical data, since it is a number. This gives the person a good idea of what percentage she made or missed, and would be a good answer if the shooter is looking to predict what chance she has of making a certain shot.

Histograms are often seen and used in math classes. They are graphs that look like a bar graph where the bars are vertical. It shows each set of data in numerical terms. Karl Pearson created the first histogram. If you want to make a histogram, first you must determine what intervals you are going to establish. The intervals could be by fives or tens or whatever number you choose. Then you need to determine the number of values that go into each set of numbers. The intervals are also called bins. These histograms are used for probability because they show probability distribution. Quality control uses histograms because it is considered to be one of the seven basic tools of quality control.
