Question

For the following set of scores:

8 6 7 5 4 10 8 9 5 7 2 9

9 10 7 8 8 7 4 6 3 8 9 6

a. Construct a frequency distribution table.

b. Sketch a histogram showing the distribution.

c. Describe the distribution using the following characteristics:

(1) What is the shape of the distribution?

(2) What score best identifies the center (average)

for the distribution?

(3) Are the scores clustered together, or are they spread out across the scale?

Answer #1

a)A frequency distribution table is

x | frequency |

2 | 1 |

3 | 1 |

4 | 2 |

5 | 2 |

6 | 3 |

7 | 4 |

8 | 5 |

9 | 4 |

10 | 2 |

b) histogram

c) histogram is

(1) The histogram moves to right side so shape of distribution is negatively skewd.

(2) The maximum frequency observed to the value of X = 8 ,so the center for the distribution is 8.

(3) We observe that all observations are concentrate near the center, so they are clusterd together.

15 students received the following scores on a quiz. 6, 7, 2,
10, 8, 6, 7, 3, 9, 5, 5, 8, 9, 8, 4
1. What is the cumulative frequency for students who scored
6?
2. How many students scored between 7 and 10?
3. What is the cumulative percentage for students who scored
9?
4. A student who received a score of 7 would be at what
percentile? (approximately)

Consider the following list of quiz scores. 2, 4, 6, 7, 7, 7, 8,
9, 10, 10 The mean score is 7. a) Two more students take the quiz.
If the mean score stays at 7, which of the following is a possible
list of the 2 additional quiz scores? b) Which of the following is
a reasonable estimate for the standard deviation in quiz score
based off of the original ten scores? c) The teacher accidentally
recorded one of...

(Note: If you’re going to subtract, choose the order medication
- placebo.)
A sample of patients with similar weight and age characteristics
were put in pairs. One patient in the pair was given medication

1.Can you calculate z-scores for each of the raw scores above?
If so, please calculate the z-score for a kid who reported spending
8 hours indoors.
2. if you transformed the variable “time spent indoors” from an
X-scale to a z-scale, what would be the new mean of the
distribution? What would be the new standard...

A frequency distribution is an organized tabulation of
the number of individuals located in each category on the scale of
measurement.
Frequency Tables:
Imagine you are a teacher and your students got the following
scores on a quiz you gave them: 8, 9, 8, 7, 10, 9, 6, 4, 9, 8, 7,
8, 10, 9, 8, 6, 9, 7, 8, 8. Place the scores in the table below
where the 1st column indicated the raw score and the
2nd column...
