Observation that we can make is min = 10, max = 19, range = 9, Maximum frequency of a number is 12, Average = 12.9, median = 12, mode = 12 it is slightly skewed on the right.
Step-by-step explanation:
- It is imperative to create a data in a tabular column before analyzing.
- Once the data is created use tally marks or frequency distribution.
- Frequency distribution helps the data to provide occurrence of event.
- Very important to number which is a counting numbers are discrete.
- Continuous of data are ones which are in decimal.
- Descriptive statistics is the 1st level of Statistics.
- It finds, where the data stands. Minimum, Maximum is understandable.
- Range is at what level data is expanded.
- Average is the one numeric of a number.
- Median is the mid point of data
- Mode is the repetitive number of the data.
- Skewness is whether data is having extreme directions.
