The graphical user interface has two views which can be toggled by clicking on one of the two tabs in the bottom left of the SPSS Statistics window. The 'Data View' shows a spreadsheet view of the cases (rows) and variables (columns). Unlike spreadsheets, the data cells can only contain numbers or text, and formulas cannot be stored in these cells. The 'Variable View' displays the metadata dictionary where each row represents a variable and shows the variable name, variable label, value label(s), print width, measurement type, and a variety of other characteristics. Cells in both views can be manually edited, defining the file structure and allowing data entry without using command syntax. This may be sufficient for small datasets. Larger datasets such as statistical surveys are more often created in data entry software, or entered during computer-assisted personal interviewing, by scanning and using optical character recognition and optical mark recognition software, or by direct capture from online questionnaires. These datasets are then read into SPSS.
Hi so this is hard to explain but im gonna give it a go!when i imported my survey data into spss it automatically assigned values to the labels but to score the data i needed to change these. so for instance very good was labelled as 1 and so on until number 4 but i need to change it so very good is 0 and so on until number 3. when i do this and go to the data view, instead of very good staying in the same place but being labelled as 0 instead of 1 what is now number 1 is in its place. i cant understand why this is happening! any help would be great this is for my thesis so it is really important its done right! thanks
how to key in data in spss 17 serial number
I am a stats TA and had a student working on some charts. She noticed that they started looking odd and called me over when we noticed the data had all been completely changed to what seemed like random numbers that meant nothing to her. She has no clue if she hit a wrong key, but her entire data set had been changed. She closed SPSS and went to re-open it and then she was unable to access her data all together. She was using an macbook when this happened. Curious if this has happened to anyone or if you know how to get this fixed. Thanks!
Do the values have to be whole numbers? I am trying to group my data such as 4.4-5 is well above average, 3.6-4.3 is somewhat above average, and so on, but SPSS will not allow it. Is there another way?ThanksNicola
Hi, I have about 15 variables which all need labelling but spss will only allow me to label 9, it would allow me to create a 10th variable. Is there any way around this or will spss only allow you to label a certain number of variables?Any help would be greatly appreciated.
There are many ways to input dates in SPSS, and a few of them are shown below. When specifying date data, you need to have a format for each of the variables. Date formats include date, adate, edate,jdate andsdate; n is one of the numeric formats. The date format is an international date; the "a" in adate means "American"; the "e" in edate means "European"; the "j" mean Julian; the "s" means sortable. Note that when entering European dates, the day is the first number given, followed by the month and the year. (See the fifth line for an example.) The sdate date format is used in many Asian countries and is sortable in its character form. The numbers with the n specify the length of the numeric variable. The default is 1. To be extra clear, the formats listed on the data list command tell SPSS what to expect when reading in the data. If you want to display the date variables in a particular format, you can use the formats command after the data have been read in.
Row number(s) to use as the column names, and the start of thedata. Default behavior is to infer the column names: if no names arepassed the behavior is identical to header=0 and column namesare inferred from the first line of the file, if column names arepassed explicitly then the behavior is identical toheader=None. Explicitly pass header=0 to be able to replaceexisting names.
The default value of None instructs pandas to guess. If the number offields in the column header row is equal to the number of fields in the bodyof the data file, then a default index is used. If it is larger, thenthe first columns are used as index so that the remaining number of fields inthe body are equal to the number of fields in the header.
Record oriented serializes the data to a JSON array of column -> value records,index labels are not included. This is useful for passing DataFrame data to plottinglibraries, for example the JavaScript library d3.js:
The extDtype key carries the name of the extension, if you have properly registeredthe ExtensionDtype, pandas will use said name to perform a lookup into the registryand re-convert the serialized data into your custom dtype.
To retrieve a single indexable or data column, use themethod select_column. This will, for example, enable you to get the indexvery quickly. These return a Series of the result, indexed by the row number.These do not currently accept the where selector.
HDFStore is not-threadsafe for writing. The underlyingPyTables only supports concurrent reads (via threading orprocesses). If you need reading and writing at the same time, youneed to serialize these operations in a single thread in a singleprocess. You will corrupt your data otherwise. See the (GH2397) for more information.
Apache Parquet provides a partitioned binary columnar serialization for data frames. It is designed tomake reading and writing data frames efficient, and to make sharing data across data analysislanguages easy. Parquet can use a variety of compression techniques to shrink the file size as much as possiblewhile still maintaining good read performance.
Similar to the parquet format, the ORC Format is a binary columnar serializationfor data frames. It is designed to make reading data frames efficient. pandas provides both the reader and the writer for theORC format, read_orc() and to_orc(). This requires the pyarrow library.
When importing categorical data, the values of the variables in the Statadata file are not preserved since Categorical variables alwaysuse integer data types between -1 and n-1 where n is the numberof categories. If the original values in the Stata data file are required,these can be imported by setting convert_categoricals=False, which willimport original data (but not the variable labels). The original values canbe matched to the imported categorical data since there is a simple mappingbetween the original Stata data values and the category codes of importedCategorical variables: missing values are assigned code -1, and thesmallest original value is assigned 0, the second smallest is assigned1 and so on until the largest original value is assigned the code n-1.
APA's general principle for rounding decimals in experimental results is as follows, quoted here for accuracy: "Round as much as possible while considering prospective use and statistical precision" (7th edition manual, p. 180). Readers can more easily understand numbers with fewer decimal places reported, and generally APA recommends rounding to two decimal places (and rescaling data if necessary to achieve this).
The screenshot below shows an example SPSS dataset I created for demonstration purposes (as you can see at the bottom of the screenshot, we are seeing the "variable view", as opposed to "data view". To review, "data view" is used for editing the actual data, whereas "variable view" is used for editing the attributes of the variables (such as number of decimal places allowed, type of variable, the variable name, variable label, and value label). In our example below, neither the variable labels (1) nor the value labels (2) have been assigned for any of our four example variables.
Produces annual national- and state-level data on the number of prisoners in state and federal prison facilities. Aggregate data are collected on race and sex of prison inmates, inmates held in private facilities and local jails, system capacity, noncitizens, and persons age 17 or younger. Findings are released in the Prisoners series and the Corrections Statistical Analysis Tool (CSAT) - Prisoners. Data are from the 50 state departments of correction, the Federal Bureau of Prisons, and until 2001, from the District of Columbia (after 2001, felons sentenced under the District of Columbia criminal code were housed in federal facilities).
One common way for the "independence" condition in a multiple linear regression model to fail is when the sample data have been collected over time and the regression model fails to effectively capture any time trends. In such a circumstance, the random errors in the model are often positively correlated over time, so that each random error is more likely to be similar to the previous random error that it would be if the random errors were independent of one another. This phenomenon is known as autocorrelation (or serial correlation) and can sometimes be detected by plotting the model residuals versus time. We'll explore this further in this section and the next.
Let yt = the annual number of worldwide earthquakes with magnitude greater than 7 on the Richter scale for n = 100 years (earthquakes.txt data obtained from ). The plot below gives a time series plot for this dataset.
In this formula, µ (the Greek letter mu) is the population mean for x, n is the number of cases (the number of values for x), and xi is the value of x for a particular case. The Greek letter sigma (Î) means summation (adding together), and the figures above and below the sigma define the range over which the operation should be performed. In this case, the notation says to sum all the values of x from 1 to n. The symbol i designates the position in the data set, so x1 is the first value in the data set, x2 the second value, and xn the last value in the data set. The summation symbol means to add together or sum the values of x from the first (x1) to the last (xn). The population mean is therefore calculated by summing all the values for the variable in question and then dividing by the number of values, remembering that dividing by n is the same thing as multiplying by 1/n. 2ff7e9595c
