Based on the previous definitions, which of the following data series represent continuous scale data?(select all applicable answers, there is more than one correct response).

A. 12 ft 9 ft 7 ft 3 ft D. 12°C 7°C 32°C 18°C

How can the boxes be observed as nominal data?

By color: Green, Orange, Blue

How can the boxes be observed as ordinal data?

By order of size: Small, Medium, Large

How can the boxes be observed as ratio scale data?

By the lengths of one side of the squares: 1cm, 2cm, 3cm

The mode is relatively easy to calculate. Assuming a standard grading scale (A=90-100, B=80-90, C=70-79, D=60-69, E<60)) what is the mode of the grades in the course, as depicted below?

C (highest bar)

Which of these is an example of INTERVAL scale data? Remember that interval scale data are continuous, however, a zero value does NOT indicate the absence of that condition. Please read each choice carefully and select the one that meets this definition.

Measurement of elevation based on sea level

Time since death is a critical concept that we discuss later in this unit. What kinds of data are depicted by the times listed in the table on the right?

interval

Consider the differences between the male and female pelvis as shown here. For a series of pelves (plural of pelvis) we would assign each to a category of 'male' or 'female'. How would the data (Male, Female) be categorized?

nominal

We will learn all about the mastoid process in unit 2 as it is one of the features used to assess the sex of an individual. This large mass of bone is located behind your ear and can be felt with your fingers. ​[12] The table on the left side is how we would record information on variation in mastoid size. What type of data is being depicted in this table?

ordinal

What types of data are being generated in this image? Note the caliper read out is in millimeters.

ratio

Based on the previous definitions of variable types, which of the following data series represent discrete data?

red, green, yellow, purple

Given the following data, what is the MEDIAN of the data set? DATA = 1, 2, 5, 4, 3, 1, 1 DOUBLE CHECK YOUR ANSWER BEFORE SUBMITTING. YOU ONLY HAVE ONE CHANCE. The answer is a whole number and no decimal places should be used.

2

Given the following data (DATA = 1, 2, 5, 4, 3, 1, 1), what is the MEAN of the data set? (Note, please provide an answer to two decimal places x.xx, rounding the second decimal place.) DOUBLE CHECK YOUR ANSWER BEFORE SUBMITTING. YOU ONLY HAVE ONE CHANCE
