What would be the most likely level of measurement for capturing variation on distance that student commute to school?  nominal ordinal interval ratio

A research study investigates the occurrence of extra heartbeats between untrained and trained older patients at risk for heart attack. Researchers decide to test whether there is a significant difference in the number of extra beats depending on training status. They obtain measurements over 10 minutes, summarized below. What did they find? If there is a significant difference, how big of one is there? (Provide a range.) dfadi = 25 (if needed) Status # patients Untrained 43 Mean # extra beats/10 min 72.46 32.35 Standard Deviation Minimum # extra beats Maximum # of extra beats Skew Kurtosis 28 165 -0.21 0.62 Trained 21 169.50 62.93 66 266 0.13 -0.1

what is the formula for finding the inter quartile range

Hellen has just started a new years competition for her local climbing gym. There are two categories for this competition: singles and group (18 people). The rules are simple, put in the most hours in one months time and you get a guided tour to climb Ten Sleep canyon. She knows from running this competition over the years that the number of hours climbers at her gym spend training during this competiton is approximately normal and their mean competition hours per month in the gym are 24 hrs with a standard devaition of 6 hrs If someone puts in between 25.5-32.1 hours on the wall they get a Mountain Goat shirt. What percent of the singles competitors is expected to get a shirt? In the group stage this year the winning group was in the 81 th percentile. What was their average time?   The group stage is up for getting Gecko Socks if they also land between 25.5-32.1 hours on the wall on average. What prercent of the groups are expected to qualify for the socks?

The mode is the only measure of central tendency that is appropriate to utilize for a variable measured with which scale of measurement? ordinal nominal interval ratio

What is the scale of measurement (type of variable) of the following variable?   Pathologic Tumor Size (cm)
