The objective of the lesson is to teach the students about the basic ideas of Data Presentation, Formation of Frequency Distribution Table, Histogram & Bar Diagram, Frequency Polygon, Percent & Relative Frequency, Frequenct Polygon & Ogive Curve etc.
After successfully completing this lesson, students should be able to:
You have your 1st quiz on 19 June, 2021 (Saturday) at 10.00amYou will get 32 minutes to complete it.
best of luck my dear students!!

The aim of the subject is to provide the student with the basic statistical tools required to analyses data encountered in a wide range of managerial situations and make effective decisions based on this data.
In addition to specific learning outcomes, the course aims to shape the attitudes of learners regarding the field of Statistics.
1. Motivate the students an intrinsic interest in statistical thinking.2. Instill the belief that Statistics is important for scientific research.3. Provide a foundation and motivation for exposure to statistical ideas subsequent to the course.

Online tools that will be used in class conduction:
1. Understand the meaning concept and objective of statistics.
2. Differentiate different types of statistics and their preliminary function.
3. Can be able to distinguish between different types of data and identify different types of variable.
4. Identify different types of variable according to their level of measurement
1. Understand how to arranged data in frequency table.
2. Have the idea to present data in informative way.
3. Understand the graphical presentation of quantitative data.
How many types of data presentations are there?
By learning central tendency students can estimate the center of the distribution in appropriate method for appropriate data.
At the end of the session participant will be able to :
Students can summarize data set according to requirement and interpret it
1. Interpret examples of methods for summarizing data sets, including summary statistics (quartiles, percentiles, deciles )
Submit here
1. To determine the reliability of the data set
2. To serve as a basis for the control of the variability.
3. To compare two or more data series.
4. To facilitate the computation of other statistical measure.
After completing the HW please submit here.
1. To know whether the distribution is normal or not
2. To have the idea about the nature and degree of concentration of observations about the mean.
3. To know the empirical relation of mean, median and mode are based on a moderately skewed distribution
4. To know the direction and extent of asymmetry in a series and permit us to compare two or more series with regard to these.
Write down the condition/s when a distribution is either symmetric, positively skewed or negatively skewed.
Exercise:
Set A: 18, 25, 10, 12.
Set B: 32, 30, 20, 10, 20, 40
Find the coefficient of skewness and comment for both the sets.

4. Calculate and interpret regression coefficients
Define Simple Regression Model with example/s.
1. Recall rudimentary mathematical properties of probability.
2. Describe the sample space for certain random experiments.
3. Explain probability in terms of long—term relative frequencies in repetitions of experiments
