# MTH 4424 ELEMENTARY STATISTICS LAB USING EXCEL COURSE PROCEDURE

### 1 Credit Hour

#### Student Level:

This course is open to students on the college level in the freshman year.

Catalog Description:

#### MTH4424 - Elementary Statistics Lab Using Excel (1 hr.)

Using Excel to construct frequency tables and histograms, compute and explore Measures of Tendency, sampling distributions, confidence intervals, and hypotheses testing. This course requires that the student have Microsoft Excel 97 or newer.

• 4.3       Compute the mean and standard deviation of a binomial distribution using
• EXCEL
• 4.5       Compute a Poisson probability distribution, which applies to occurrences of some event over a specific interval, and its probabilities using EXCEL.

#### UNIT 5: Normal Probability Distributions        Section 5.1 - 5.7

Outcomes: The student will use EXCEL to explore continuous probability distributions and focus on the most important category: normal distributions.

#### Text Book:

Contact the Bookstore for current textbook.

#### Materials/Equipment needed:

Computer with EXCEL 97 or above and Internet access

#### Attendance Policy:

Students should adhere to the attendance policy outlined by the instructor in the course syllabus.

The grading policy will be outlined by the instructor in the course syllabus.

#### Maximum class size:

Based on classroom occupancy

#### Course Timeframe:

The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college. A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time. The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
