The following histogram represents the marks of students in the mid term examination. The y-axis represents the number of students who scored the marks represented on the a-axis. Determine the range of marks that contains the fewest number of students. DRAG & DROP THE ANSWER 60 - 69 10 - 19 Midterm exam scores 20-29 70 - 79 0-9 10-19 20-29 30-39 40-49 50-59 60-69 70-79 Number of students
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
